Answer 1

Answer:

a) (– 8) + _____ = 0

Since we know that, -a +a =0. Therefore, the blank space should be + 8.

(b) 13 + _____ = 0

The sum is zero. Therefore it should be additive inverse of 13. \Rightarrow -13( is the answer)

(c) 12 + (– 12) = ____

Since we know that, -a +a =0 So, the answer is Zero (0)

(d) (– 4) + ____ = – 12

The integer in blank space should be -8

(e) ____ – 15 = – 10

The integer in blank space should be +5
