Find the value of $(- 15) - (- 18)$

Open in App

Solution

Let's find the value of $(- 15) - (- 18)$ :
To subtract an integer $b$ from another integer $a$ , we add the additive inverse of $b$ to $a$ . So, $a - b = a + (- b)$ .
We have, $(- 15) - (- 18)$ .
$= (- 15) + 18$ ( the additive inverse of $- 18$ is $18$ )
$= 3$ ( to add a negative and a positive integer, we subtract the absolute values of both integers and put the sign of the number with greater absolute value to the result)

Hence, $(- 15) - (- 18) = 3$ .
