Fill in the blanks.
(a) (– 8) + _____ = 0
(b) 13 + _____ = 0
(c) 12 + (– 12) = ____
(d) (– 4) + ____ = – 12
(e) ____ – 15 = – 10

Solution:

We use the concepts of positive and negative integers and addition and subtraction to fill in the blanks. We know that when we add a number to its additive inverse, we get 0 as the answer.

(a) Additive Inverse of - 8 = 8
So, - 8 + 8 = 0
Therefore, 8 is the answer.

(b) Additive inverse of 13 = -13
So, 13 + (-13) = 0
Therefore, -13 is the answer.

(c) Here we are adding 12 to its additive inverse, i.e -12
12 + (-12) = 0
Therefore, 0 is the answer.

(d) Here, we have to find what we need to add to -4 to get -12. So, to find the missing value, let’s add 4 to both sides of the equation.
- 4 + 4 + ___ = -12 +4
0 + ___ = - 8
___ = - 8
Therefore, -8 is the answer.

(e) Here to find the missing value, we need to first add 15 to both sides of the equation.
____ - 15 +15 = -10 +15
___ + 0 = 5
___ = 5
Therefore, 5 is the answer.
