QUESTION 1:

8 + (-2) - (-6) = 8 - 2 + 6 = 6 + 6 = 12.

8 + (-2) is the same as subtracting 2 from 8 to get 6.

6 - (-6) is the same as adding 6 to 6 to get 12.

positive plus negative is the same as positive minus positive with the sign of the result coming from the larger operand.
positive minus negative is the same as positive + positive with the sign of the result always being positive.

QUESTION 2:

3*(-6) + (-7)*(-10) = -18 + 70 = 52.

3*(-6) will always be negative because a plus times a minus is always minus.

(-7)*(-10) will always be positive because a minus times a minus is always positive.

-18 plus 70 is the same as 70 minus 18 = 52.

positive times negative will always be negative.
negative times negative will always be positive.
negative plus positive is the same as positive plus negative is the same as positive minus positive with the sign of the result coming from the larger operand.
