Question

add -13 + 5.
-8
-18
18
8

Explanation:

Step1: Recall integer addition rule

For adding a negative and a positive number, we subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value. Here, \(|-13| = 13\) and \(|5| = 5\). Since \(13>5\), we subtract \(5\) from \(13\): \(13 - 5 = 8\).

Step2: Determine the sign

The number with the larger absolute value is \(-13\), which is negative, so the result will be negative. Thus, \(-13 + 5=-8\).

Answer:

-8 (corresponding to the option with -8)
