Capitolo 1, Problema 25
Find each sum or difference. See Example 1. 8 - (-13)
Guida verificata passo dopo passo1
Recognize that the problem involves subtracting a negative number: \(8 - (-13)\).
Recall the rule that subtracting a negative number is equivalent to adding its positive counterpart, so rewrite the expression as \(8 + 13\).
Perform the addition operation by combining the two positive numbers.
Write the final expression clearly as \(8 + 13\) to show the sum.
Understand that this step simplifies the original problem by converting subtraction of a negative into addition, which is easier to compute.
