evaluate the following.\n(a) $|2|-7=square$\n(b) $|2 - 7|=square$

Explanation:

Step1: Calculate absolute - value in (a)

The absolute value of 2 is 2, so (|2| = 2). Then (|2|-7=2 - 7).

Step2: Perform subtraction in (a)

(2-7=-5).

Step3: Calculate the expression inside the absolute - value in (b)

First, calculate (2 - 7=-5). Then find the absolute value of (-5), so (|2 - 7|=|-5|).

Step4: Calculate absolute - value in (b)

The absolute value of (-5) is 5, so (|-5| = 5).

Answer:

(a) - 5 (b) 5
