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.

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

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.

So if you deposit 5M into your account today... That's 5M

Then tomorrow, you went to the bank, pick up a slip and filled the amount with zero naira...that's
N0... Which is N5M x N0 you've deposited...

Then you went to withdraw on Monday and the cashier tells you your account is empty base on sey you deposit N5m, come deposit zero naira on top, mathematically your N5M don vanish because of the zero naira you deposit.... Abeg the teller is right bah? You go let go bah? grin

2x3 = 0+3+3 = 6

Or

2x3 = 2+2+2 = 6

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)

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.

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

2x3 = 0+3+3 = 6

Or

2x3 = 2+2+2 = 6

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.)

I have had some excellent results mentoring some young mathematicians who hated mathematics prior to my intervention.

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.

mind you
0 * 3 and
3 * 0 are two different statement.

0 (nothing) * 3 (something) = 0 (nothing)


3 (something) * 0 (nothing) = 0 (nothing).

why isnt it
3 * 0 = 3
0 * 3 = 0
In logic there is a saying u cant build something on nothing, likewise u cant build nothing on something.

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

This translate to zero 0 (if i dont have 1 naira) * 1 or * 100 = 0 (i still dont have any)

NOW THIS

(You have) 100 * 0 (nothing) = 0 (nothing)
translate to you have 100 and i ask zero time(simply i dont ask) and then you loose your 100

so how do you explain this?
losing you 100 when you do nothing
What it really means is 100people(something) * 0people(nothing) = nothing.
Either ways u can still say 0people(nothing) * 100people(something) = nothing.

Re: Why Is Any Number Multiplied By Zero Equals To Zero? by koning: 10:50pm On Jan 14, 2021

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.

Better still, If they deposit N10m in an interest yeilding account. End of the month, the account yeilded 0 interest. Will they then accept 0 capital as deposit?. Since N10m x 0 =0.

Going by this logic, in the second case, the hundred naira availability is not the issue but the 'receiving' aspect. Mathematics deal with the resultant effect of an action or an inaction.

OP, the multiplication operation is simply repeated addition and it is also commutative. Hence, 0 × 5 = 5 × 0 = 0 + 0 + 0 + 0 + 0 = 5 in zero place = 0.

Withdrawing in this case is minus. That is, N10m - N0 = N10m.
