-4 + (-16) = -4 - 16 = -20
-1/16 + 5/16 = 4/16 = 1/4
16 + -5 =
- 12 + 4 = - 8
(5r - 4)(5r + 4)
It is: -16+(-14) = -30
-16 + - 40 = -(16 + 40) = -56
Sweetie, when you subtract a negative, it's like adding a positive. So, 16 minus negative 4 is the same as 16 plus 4, which equals 20. Math doesn't have to be a drama, darling.

-4 X -4 = (+)16 Remember the table multiplying/dividing negative/positive numbers. X + = + X - = - X + = - X - = + NB If no sign is before the number, then read it as 'plus(+)'.
