1. Why does -6 - (-2) = -4? Be clear and complete.

-6 - (-2) = -4

Multiply the negative sign with the term inside the bracket.
Negative x negative = positive

-6 + 2 = -4

-6 + 2 = 4

The sign of the great number is written with the answer. In this case, 6 is the greater number and its sign is negative.

-4 = -4
