Dear Lord, 8 year old in secondary school? Where are you running to? My 9 yr old is in pry 5 and i think she s still early. Let the kid develop all round, not only education pls.

But really, a 9yr old in primary 5 and the op's 8yr in primary 4 is the same. That means Nursery 1 at 2yrs. Over 50% of kids aged 2 are still "tata". Do you know that the best age to stop breastfeeding is 2yrs. What then is prenursery and day care?

Recommended school age is 6-12yrs every where in the world with the earliest 5-11yrs

We are still very guilty of pushing kids.

I'm not selling anything. I hookup people who want to get together. Whether they date, become besties or just have sex it's not my decision to make.

And what's in for you?

You are a love-vendor on the side abi, any na hustle.

There was a protest that turned into violence at Kafanchan District of Kaduna Electric today. One life was lost and others in the hospital while the company lost vehicles and office properties.

The problems were outrageous billing and a 1new manager that reduced the power supply to the town.

I wonder what happened to the energy capping that NERC introduced last year April.

Cross tour is a NO for me. I don't know about others but seeing 2 accidental Crosstours when it just started coming into the country got me pissed off. He should think Benz or Volvo if he wants an uncommon luxury.

Knowing 3 people that had their Venza stolen and 5 others that got kidnapped or attempted because they drove Venza, would you say Venza is a bad car?

One car I have seen so many of it's scrap is a Peugeot 206, but people still buy it.

A friend summersaulted in his 2006 Tacoma 3 whole times, apart from engine overheat and AC trauma. Would you say Tacoma is a bad car?

At the very least he should have a third party insurance card.

Marriage might not be your cup of tea.
But if what you typed is what marriage is about, then no one will get married.
Re-orient yourself.

People go still marry o. Procreation in mind.

Those who don't have the experience will do it. Like children actually have to get hurt before before the keep away from fire or hot things.

How's she doing now

You know what you are writing about. However, without directed numbers most mathematical problems cannot be solved

That's obvious.

BlackFlamefromP:
Op, don't confuse yourself. It is IMPOSSIBLE to multiply tangible, physical things by zero! To multiply anything by zero simply means that thing never existed and doesn't exist.

Example, if you have 12 oranges in 1 basket (that is 12*1) that will give you 12 oranges. If you have 12 oranges in 3 baskets you have 36 oranges (12*3 or 3*12 - is the same).

Now if you have 12 oranges in 0 basket what that simply means is that there is no basket anywhere where you have 12 oranges meaning there is no 12 oranges anywhere, hence, you have 0 orange (12*0 = 0)

Gbaaaaammm!!!

That's the answer I have tried to put across.

Reality deals only with Natural numbers.

I don't get When did nairaland become Quora or Reddit Honestly I only come across these sort of intelligent question on those platforms.

Kudos to some guys here..So many geniuses everywhere. Justice has been done to the question really.

Any intelligent question you ever seen on NL, there are over 10 similar questions on Quora or Reddit

I have seen very similar questions on Quora after seeing this thread

Walexybobo:
And y do you have to forget that the counting of number start with Zero? It simply mean that every figure no matter how big or small will surely come back to zero.
Moral of life:- thou was created from the dust and shall return wheather you are rich or poor.

Na so them teach you to count, starting from zero

TheGoodJoe:
There is no multiplication in this case. That is addition. You deposited N10m and N0.

That is 10 + 0 = 10. You still have N10m in the account.

No mind am abeg, his moniker is offpoint.

Angrymode:
My question is why are negative numbers also regarded as real number

In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line.

The "real" is not in the contextual sense of the word reality or real.

teepain:
There are no constants in multiplication, hence the position of the factors of multiplication cannot affect the product of the numbers (commutative law of multiplication) who said it did?

The division of numbers does not obey the commutative law, hence the position of the numerator and denominator affects the final answer, hence 3/5 is not equal to 5/3. who said it did?


A child will grab whichever you present to him or her. But the most important thing is to present the concept that can answer most questions that may arise (the original post refers.) children who count with fingers, toes, stones and tally will be confused at your introduction of 0 to multiplication, I am sure your math skills wasn't taught to you at once

I have had some excellent results mentoring some young mathematicians who hated mathematics prior to my intervention. do I sound like I care about your chest beating

You didn't answer how you apply commutative law of multiplication in real life.

Why all the prawness but not the real question op asked? Is the question not clear enough? Are my comments not comprehensible enough that you deviate so much to show me your prawness?

A child in a good school primary 1 can count 1, 2, 3.....1000....., He will add, subtract, multiply and divide numbers in tens, hundreds, thousands but will not know the concept of zero. You will never see in their text books at such level where zero is a factor in multiplication or division. Zero is a concept that at your level, you comprehend but not at all levels and not everyone has the skill.

A market woman who never went to a formal school, cannot read nor write will do all the simple arithmetic with money but will not understand what Zero Naira means. She has never seen it nor encountered it anywhere in the market. If she was asked how many oranges she sold today, you will not hear "zero!" the usual answer is "not 1!"

Perhaps your studies in mathematics has taken you to very complex levels that to imagine what it means for real has been blurred. With all the math you know, I believe you need to research about zero because this isn't a new topic.

If you don't get the point at this point, all my further comments will still not be understood so I leave you to what you know.

If you have not heard the saying, hear it, "zero is to math, as black is to colour".

studentofTruth:
You obviously didn't understand my post. Go back and read it again, but slowly this time so that you grab it.

I was making a case that the product of multiplication is zero because the action never happened (zero action), and not that the non-zero element disappeared. The entire case was that the non-zero element (the 10 oranges, the 10 persons, the surgeon and his skills, or the fund manager's cash) is still very much present and never at any point ceased to exist! You misunderstood my post. Go and read it again.


What I'm countering in your post is saying that zero is abstract. Zero means the absence/lack of value. The absence of something doesn't make it abstract.

Don't cease to exist = never disappeared.

Are you aware that Zero is a concept and was actually created with civilization. Zero does have a complex history and use.

Have you been close to children? They teach children to count numerically 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

At what point are they taught the value of of Zero? Check the pictures below, these are typical multiplication tables. Ask yourself why Zero is not there.

1 has a value in reality
0 has no value in reality
-1 has no value in reality

The problem is you know math and understand what zero is, but to the person who has not been a math studént will not understand what 0 is because it has no value in real life.

What are natural numbers in math, they are 1, 2 ,3......
what are imaginary numbers .... -3, -2, -1

Where is zero, even mathematics knows zero is abstract

teepain:
Going by the commutative law of multiplication, 2x0 = 0x2

Therefore, you can read 0x2 to mean 2 times we add 0. Rearranging numbers to solve or explain mathematical concepts is an agelong and acceptable practice amongst mathematicians.

Alternatively, if you don't want to rearrange you can read 0x2 as:

0 times we add 2 to zero (using zero as the starting point of your number). Which would still give you 0.

By the same token;
2x0 can be read as 2 times we add 0 to zero:

Zero + 0 + 0 = 0

1 x 3 reads 1 time we add 3 to 0
0 + 3 = 3

2 x 3 reads 2 times we add 3 to 0:
0 + 3 + 3 = 6

0 x 3 reads 0 times we add 3 to 0:
0 = 0 (because we didn't add any 3 to 0)

How do you apply commutative law of multiplication in real life?

Of course, 0x2 is 2x0.

Both 0 and 2 are factors of the multiplication but the first number is the constant and the second is the multiplier.

In division, same applies, the first number is the numerator and the second the divisor or denominator.

2x3 | 2+2+2
4÷2 | 4/2

Which of these do you think a child will grasp easier?

2x3 = 0+3+3 = 6

Or

2x3 = 2+2+2 = 6

studentofTruth:
That's what gives it the zero value. Action carried out is 0. But the oranges don't cease to exist


In the case of the surgeon, the fact that the action didn't happen gives that action a zero value (no action).

Action carried out in abstract can be zero but action carried out in reality is no action, that means the action never happened or not going to happen. That is the implication not disappearance of oranges like you insinuate.

I have 10 oranges and gave out zero oranges.

That is 10 x 0=0

In reality the zero means the giving out never happened so you still have the 10 oranges. That means its impossible to give out nothing in reality

In reality, we are not talking about value we are talking about real objects and actions. The value you are talking about is still abstract.

What is the value of zero in reality, nothing. What is the value of nothing in reality, it is still nothing. Nothing in the real sense of it is non existent.

Simply put, zero is an abstract value for nothing in reality.

studentofTruth:
It is not. See this explanation:

Back to your question, I will attempt to explain it using Einstein's general relativity theory. "Everything is relative to something else." In the case of anything multiplied by zero giving a product of zero, that "zero" product is relative to the action and not the entities multiplied — the product being zero doesn't mean that the non-zero entity vanished.

Let me explain with your oranges example:
First scenario (10x0 = 0): You have 10 oranges to give out. The action here is "to give out 10 oranges." To complete this action, there must be 10 oranges to give out and someone or something to give them to. In this case, you have the 10 oranges, but there's nobody/nothing to give the oranges. Relative to the intended action — giving out 10 oranges — you have given out zero oranges. However, it does not mean that the entity (10 oranges) vanished. In other words, the fact that the second entity needed to complete the action is not there (value: 0) doesn't mean that the first entity (10 oranges) has vanished. It only means that the action cannot be carried out (value: 0).

To put it as an equation:

Entity1(Present) x Entity2(Absent) = Action(Absent)

Second scenario (0x10 = 0): You want to give out oranges to 10 persons. The action is "to give out oranges to 10 persons." To complete the action, you must have both entities — the oranges to give out and the 10 persons you will give the oranges. But you have no (zero) oranges, so the action cannot be carried out. Relative to the action — giving out oranges — you have done nothing (zero oranges given out). However, this doesn't mean that the 10 persons vanished because there were no oranges. In other words, the fact that the other entity needed to complete the action is not there (value: 0) doesn't mean that the second entity (10 persons) has vanished. It only means that the action cannot be carried out (value: 0).

To put it as an equation:

Entity1(Absent) x Entity2(Present) = Action(Absent)


The point I'm making is that, using general relativity theory, the product of any multiplication with zero relative to the action and not the entities in the multiplication. The absence of any of the entities means that the action cannot be carried out, but the other entities don't cease to exit.

So, even in cases of 10x2x0 = 0, you can extend this logic to explain it.

An example of everyday application of this can be seen in anything. If there's no patient to be operated, the surgeon carries out no surgery, but it doesn't mean that the doctor or his surgical skills have vanished.
If a fund manager sees no good opportunity to invest in, no investment happens, but that doesn't mean that the fund manager or the cash has vanished. This is why cash is a component of any portfolio — it stays there waiting for the right opportunity to go make you more money.

I see no difference between you and I.

The second bolded means you can't give 10 oranges to no one in reality.

A surgeon can't operate on no one

A fund manager cannot invest on nothing

If 5 surgeons did 10 surgeries, they all did 50 surgeries
5x10=50

But if 5 did nothing we have no surgery. The action (surgery) didn't happen

5x0=0

Can we say a surgery happened?

TheGoodJoe:
I think I have noticed where the confusion is coming from.

When it comes to multiplications, the discussion should start from the product and not the factors.

For example,
You want to produce dresses for girls in a class.

How many dresses do you need to Produce?

This is when the factors are considered.

50 girls and 2 dresses each.

That becomes 50 X 2 = 100 dresses.


If there are no girls to produce dresses, even if you want to produce 2 each, you can't Produce any, which is zero.

0 X 2 = 0.

Finally even if there are 50 girls but they are not going to collect any, how many will he Produce, none, zero.

50 X 0 = 0


BobFischer, Dtruthspeaker, teepain, mu2sa2, adanny02, koning, STINOS, iWise

Totally agree

teepain:
Basically, multiplication means to add a number of times.

For instance, 3x7 means 3 times 7. The 3 times 7 actually means 3 times (we add) 7.

Hence, 7x3 = 7 + 7 + 7 = 21.

In the same vein, 5 x 0, means 5 times we add 0 or add 0 in 5 places.

Hence, 5 x 0 = 0 + 0 + 0 + 0 + 0 = 0

Because of the commutative law of multiplication, which states that the order in which a set of numbers are multiplied does not affect their product,

5 x 0 = 0 x 5

Therefore, regardless of the order you will have zero as your answer if you multiplied any number by zero.

CC: TheGoodJoe, mu2sa2, adanny02

Sure

If I must reply,

3 x 7 means 3 times 7 or 3 by 7

This means we add 3 up to 7times

3+3+3+3+3+3+3=21

This is why the primary school multiplication table is arranged separately for each number

2x1=2 | 2
2x2=4 | 2+2
2x3=6 | 2+2+2
2x4=8 | 2+2+2+2

The question is how will you write

2x0 | ?

You can write

0x2 | 0+0

It is easier to explain 0x2 than 2x0

0x2 is twice of nothing
2x0 is nothing of two things

Take 2 real oranges in your hands for instance, in what scenario will you multiply them so that they turn to zero or nothing? I guess you can't except by magic.

That means the concept of zero or nothing is purely a figment of imagination and purely abstract.

smartty68:
0 * 10 oranges at hand = 10 oranges... Reasons being that the oranges won't mysteriously disappear from my hand...

Imagine multiplying the 6 luggage bags by 0 and yet the load from the luggage still on you...

That will be wrong.

The right answer is still a flat zero.

Imagine it this way, zero is a virus or magic that causes real things to disappear.

In real life, imagine the situation where you will need to multiply, 10oranges by zero. That real situation doesn't exist because zero doesn't exist in the real.

You have 10 oranges,

10 oranges x ? = nothing

You will find out that there is nothing that can be multiplied to 10oranges for them to become nothing.

i.e 10 oranges x nothing = nothing

But 10 oranges x something = something
You

BobFischer:
Why is any any number multiply by zero is equal to zero?

10 x 0 = 0
100 x 0 = 0
1000 x 0 = 0

If i have 100 oranges on a table and i multiply it by zero. Why do i suddenly have zero?

100 oranges X 0 = 0
1000 pears X 0 = 0


front page please
mathematicians in the house please gather.

It's like saying, I have built a house but need a foundation for it.

Your have to differentiate what is real and what is abstract.

In the real sense, you can't have a house without a foundation but in abstract you can.

In real maths, 1 real orange cannot be multiplied by zero because the multiplier if zero does not exist. The multiplier could be people, baskets etc these multiplier has to exist so cannot be zero.

Another way to explain it is, 1 orange x 0 people means the event never happened or will never happen. This means the event is just abstract.

Zero is abstract and means nothing in real life. In fact, there is no zero in real life
it is totally abstract.

You can press a horn 1 beep or 2 beep but 0 beep means you never pressed the horn.

Zero is just a concept.

The Only Christian Monarch In The whole Northeast ‘Mai Tangale’ Dies At 72.................. What can you deduce from this caption?

What did you deduce from my first sentence?

Even though the information may not be entirely accurate,

salbis:
. He is not the only first class Christian traditional ruler in the NE. These are first class Monarchs in Adamawa; Hama Bachama, Hama Bata, Kwandi Nguryaba of Guyuk and Murum Mbula

Even though the information may not be entirely accurate, it may make a little sense as to the level of this traditional ruler. I know the Billiri people and also the Bachama but others on your list may not as popular. Again, I have encountered more Billiri people than Bachama so I believe the Tangale chiefdom should be larger and maybe actually the biggest Christian chiefdom in the North East.

In Kaduna, we have a first class Emir whose chiefdom is within 2 urban wards. This Emir cannot be compared to the Emir of Zauzzau.

Racoon:
Guess OP means-Billiri, Gombe State? Once had an ECWA national youth conference there before the one in Egbe. Whao! The only first class Christain traditional ruler in NE? Well, you have spent you time well given the OP testimony.Rest on sir.

Watch what will happen now, if there is a Muslim in his family or another ruling family, the Governor will even ignore kingmakers in favour of a Muslim.
