3. Fill in the blanks.
(a) (– 8) + _____ = 0
(b) 13 + _____ = 0
(c) 12 + (– 12) = ____
(d) (– 4) + ____ = – 12
(e) ____ – 15 = – 10
a) (– 8) + _____ = 0
Since we know that, . Therefore, the blank space should be + 8.
(b) 13 + _____ = 0
The sum is zero. Therefore it should be additive inverse of 13. -13( is the answer)
(c) 12 + (– 12) = ____
Since we know that, 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
(a) (– 8) + (+8) = 0
(b)+13 + (-13) = 0
(c) 12 + (– 12) = 0
(d) (– 4) + (-8) = – 12
(e) +5 – 15 = – 10
