Solution

Find the value of $(- 32) - (- 40)$ :
To subtract an integer $b$ from another integer $a$ , we add the additive inverse of $b$ to $a$ . So, $a - b = a + (- b)$ .
The additive inverse of $- 40$ is $40$ .
So, $(- 32) - (- 40)$ $= (- 32) + 40$
To add a negative and a positive integer, we subtract the absolute value of the greater integer from the smaller and put the sign of the number with the greater absolute value to the result.
So, $(- 32) + 40$ $= 8$ .

Hence, the value of the given expression is $8$ .
