Answer 1

Answer:

2×2 =4

(-2)×(-2)=4

Step-by-step explanation:

Because when the number of negative terms in multiplication are in even then we will get positive number and when we have odd number of negative terms we will get negative number.

For Example (-2)×(-2)(-2)= -8

We have odd number of negative terms so the product is negative.
