BobFischer:


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

You're getting it wrong. Multiplication obeys associative and commutative property... i.e, A*B = B*A

Therefore, 3*0 = 0*3

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

Here's the logic:
1 + 1 = 2 (result)
The two is the result when you add another one to the one you have before
2 × 2 = result = 4 (we increase to by itself twice (multiply or multiple))
2 × 3 = result = 6 (we increase two three times I.e two increases itself 3 times)
2 * 0 = result = 0 (two increases itself by nothing so there will be no result )
If you have 100 oranges and you try to increase that 100 oranges by nothing you will have no result (nothing)
Will your 100 oranges still be there? Yes but on the left hand side of the equation but on the right hand side there's no result (0)
100 oranges × 0 (left hand side of equation) = result(0) (right hand side of the equation)
Simply put, when you try to increase(multiply) yourself by nothing, you get nothing

For addition and subtraction you are not trying to increase(multiply) yourself but you're either bringing several of your twin/family members to join you or removing your twin/family members wey you don take join body before.

Shay you get the simple logic

. Still doesn't make much sense to me sir/ma........I don't have any problem believing that 0*30=0 because logically one can say that nothing in 30 places will always be nothing,but I find it almost impossible to believe that 30*0 =0......what is the logical explanation to convince a man who has 30# that because his 30# was multiple by nothing (0) and as such he has no money again?.it doesn't add up.



Going by ur logic, 2*3=6

Now 2 oranges* 3 apple =?


Mathematically it doesn't go as the way you are proofing ur theory

Zero practically means nothing.

So nothing 1 time, nothing 2 times and nothing 1000 times 0r 1million times is still equal to nothing.

Eg) if i dont have 1 naira, if you ask me for 1 naira for 1 time or even 100 times, i still dont have any. that is it.

Op, to answer your question, assume zero to mean nothings/zilch/nada

If you have nothing, and you times it by something, the most intuitive answer is nothing.

STINOS:
First the commonsense explanation:

Say you are giving away free apples. An infinitely big apple tree has sprouted in your garden (it's hypothetical) and you have decided to give away apples to each person who comes by. You have decided that you'll give 1 apple to each person that comes by. If one person comes by, you have given away one apple. If two people come by, you have given away two apples. If seventy-five people come by you have given away seventy-five apples. This is multiplication by 1. If there are n people that come by, 1*n tells you how many apples you have given away.

Say you are giving away 2 apples per person. If one person comes by, you have given away two apples. If two people come by you have given away four apples. If thirty people come by you have given away sixty apples. This is multiplication by 2. So if 'n' is how many people came by, 2*n tells you how many apples you have given away.

Similarly, if you are giving away 100 apples per person, 100*n tells you how many apples you have given away in total where 'n' is how many people came by to collect their apples (everyone loves apples).

If you are giving away 0 apples per person, then regardless of how many people come by, how many apples would you have given out by the end of the day? Logically? None, of course! Hence, 0*n = 0.

This also works the other way around, because of the commutative law for multiplication. So lets say no people come by, i.e., n = 0. Regardless of how many apples you want to give away, the total number of apples you have given away will always be 0. Cause no one comes by to take the apples! So a*0 = 0 where a is how many apples you give away per person, which doesn't matter.

Now for an explanation hinging slightly more on mathematical notation:


Multiplication is basically addition, done over and over again. Multiplying a number n by 2 means adding n twice --> n + n

Multiplying a number by 7 means adding it seven times --> n + n + n + n + n + n + n

Multiplying a number a gazillion times means n + n + n ... (a gazillion n's)

So what you multiply 'n' by tells you the number of n you have to add together. If you multiply n by 0, then there are no n's in the picture. Since you are not adding anything, you are left with nothing, aka 0. So:

2*n = n + n (two n's on this side)
7*n = n + n + n + n + n + n + n (seven n's on this side)
0*n = (how many n's do you see on this side? None.
Genius well done sir I get it

Yes something changed.
In the first equation, two is the one increasing itself ten times, while in the second equation ten is the one increasing itself two times. Even though their results are the same, they went through different processes to arrive at that same result. Two went through a longer process than ten in the second equation. Shay you get?

Zero means nothing. When you multiply any thing by nothing it gives nothing.

That's the law.

Not true!! We should be ready to ask questions. God gave a reason why we shouldn't kill . He didn't just gave the law. The reason came before the law Genesis 9:6 , Deuteronomy 12: 23. We obtain knowledge by asking questions and God permit.
And there's a mathematical explanation for his questions. Read through the comments

Multiplication is simply a repetition of addition.
Meaning: 2*3=2+2+2=6,
Also 3*2=3+3=6,

4*2=4+4=8,
Also, 2*4=2+2+2+2=8

This implied that multiplication is commutative,
I.e M*N=N*M

Thus: 0*6=0+0+0+0+0+0=0
Also 6*0=0

Zero is nothing. If you follow the concept of multiplication, you will see that nothing in any amount of quantity remains nothing. Zero is for and signifies emptiness or nothingness.

nairaman66:


An example of 'mathematical proof'

I realize you don't want too much mathematics, but I'd like to point out that it is rather trivial to "prove", using only the basic few axioms (up to the distributive law)

I suppose you do not need much convincing that 0 + 0 = 0 (which itself is a consequence of the additive identity n + 0 = a, with a = 0)

Now, as per the distributive law, n * (b+c) = n*b + n*c

(b and c are two other arbitrary numbers. So there are b oranges and c apples in a bag. A bag is (b+c). If you buy 2 bags, then you get twice the number of oranges and twice the number of apples --> 2(b+c) = 2b + 2c.)

And so n*0 = n* (0+0) = n*0 + n*0, (from the previous bit)

So n*0 = n*0 + n*0

Subtract (n*0) from both sides, giving

0 = n*0

N.B Quora

You could as well exploit the existence of inverses: for each element in a group, there exists a unique element such that: a•b == i, where i is the identity element of the group, and • is an operation on the group elements.

For addition operation, 0 is the identity element and the additive inverse of any element a is -a : a + (-a) = 0.

Using the distributive law:

n*0 = n * (a + (-a)) = n*a + (n*-a) = n*a - n*a = 0.

Thus, n*0 = 0 is basically the consequence of the existence of an additive identity/inverses + the distributive law.
