Question

(a) $|-6| + 7 = square$ (b) $|-6 + 7| = square$

Explanation:

Step1: Evaluate absolute - value of - 6

The absolute value of - 6, $|-6| = 6$. So for (a), we have $6 + 7$.

Step2: Calculate the sum for (a)

$6+7=13$.

Step3: Calculate the value inside the absolute - value for (b)

First, calculate $-6 + 7=1$.

Step4: Evaluate the absolute - value for (b)

Since the value inside the absolute - value is 1, $|1| = 1$.

Answer:

(a) 13
(b) 1
