How come 0*anything(4) is 0 and 4*0 is also 0?

Question

Hey, people, answer seriously. 0(zero) means nothing. According to the law, energy can neither be created nor destroyed. So, nothingness cannot be increased in the universe. So, it should be undefined. Zero times 4 is zero, but there can't be a '4 times zero.' You can't have 4 times nothing.

Answer 1

Multiplication can be defined as repeated additions.

0 + 0 + 0 + 0 = 0 means four zero's add to zero, or 4 × 0 = 0.

Answer 2

zero is a number . Say that zero is nothing, can be, but not in mathematics.
That is abstract: I am going to try to write something concrete.

0+0+0+0 = 0 (No problem with this)

How you can write 4 zero times? Suppose in zero days of your life you are going to see 4 Dolores in only one paper since now, we don´'t have.
This is one example that is difficult to make something concrete.

Another point: (-2) X (-4) Try to explain that or (-4) X (-2).

Write something zero times or negative time is something very interesting.

My suggestion is that you read something about math history.

If you have a translator try to write this question in other languages. I mean send to people from another country.

(-2) x 4 = -8
(-1) X4= -4
0x 4 = 0
1x4 = 1
...

you what to prove in NUMBER THEORY that 4x0 have the same result them 0x4, in this Way you can have a chance to understand.

Answer 3

When multiplying you have two factors is one of those factors are nothing you are saying you have 0 fours. (example you have zero cows ) Its the same thing you just simple don't have any of that number. Now if you reverse it all your doing is saying you have 4's but zero of them (you sell cows but have zero at the moment) no matter if you reverse the numbers your saying the same thing. The statement just holds true either way and nothing will change.

Answer 4

If you accept that zero is a number, then 4*0 = 0 has to be true.
If it were any other value, it would be consistant with the rest of your arithmetic.

Answer 5

Of course you can have four times nothing. It's like this: I have 4 pockets, and I have nothing in each of those pockets. Then when I combine the contents of those 4 pockets, then what I have is 4 times nothing, and all that still adds up to nothing. See how that works out, Camillia?

Answer 6

Zero doesn't mean nothing, it means no value (e.g. no energy, no weight, etc.). A piece of paper in the size of 1 dollar is not a dollar but just a piece of paper, something of no value. If you have 4 such papers it doesn't make you richer... you still have 4 times something of no value.

Answer 7

APPEAR IN THE EXAM FOUR TIMES AND EVERY TIMES YOU ARE GETTING NOTHING(ZERO).
NOTHING+NOTHING +NOTHING+NOTHING+NOTHING
=NOTHING(1+1+1+1)=NOTHING(4)
=ZERO(4) ,AS YOU HAVE GIVEN 0 MEANS NOTHING.
=0
SO YOU CAN HAVE FOUR TIMES NOTHING(I MEAN ZERO)

Answer 8

Four times some quantity... If you have nothing in your hand, and you hold your hand out four times and ask how much that was, how much have you had in your hand? Wouldn't that be 4*0?

In mathematics this is called "Commutative Property of Multiplication": a*b = b*a.

Answer 9

because you forgot to unlock the needle of your caliper thats why you got 0 on a 4 inches standards

Answer 10

Sure you can. Take a can with 'nothing' in it. Now if you have four of these cans, you have 4 * 'nothing' and you still have nothing.
