Why is 0 divided by 0 undefined?

Answer 1

Undefined: You cannot divide by zero

Answer 2

The answer of a division problem can be proved by using multiplication (the inverse operation). For example, 8 divided by 4 is 2, because 2 times 4 is 8. Notice how the order of the numbers is reversed. When you divide by zero, you have a problem. First consider the answer to the problem 8 divided by 0. It would be the number that works in ? times 0 is 8. But anything times 0 is 0, not 8, so this problem has no answer. Now consider 0 divided by 0. The answer to this problem is the number that works in ?times 0 is 0. Every number is an answer! You can't pick or "define" the number that is the one answer to this problem, so it is said that the problem 0 divided by 0 is "undefined".

not sure why its returning as undefined (guessing on a calculator) but you CAN'T divide by zero, the world will end
