Question

Why is the answer actually 1 not 0​

Answer 1

Any number divided by itself is 1.

Explanation:

One of the nice parts about algebra is that -- if a number appears more than once -- you can make things a lot cleaner looking by throwing them in a variable. Let's let x = -2² . Our equation then becomes x ÷ x = 1, and it's much clearer here that, since we're dividing x by itself, the answer should clearly be one.

Answer 2

-2^2÷ -2^2=1

(-2)(-2)÷ (-2)(-2)=1

4 ÷4=1

Answer is 1
