Question

Pls help me ASAP!

Evaluate the following

a: |8| - 9 =
b: |8 - 9| =

Answer 1

a = -1

b= 1

Explanation:

8's absolute value is 8, so 8 - 9 is -1 but 8-9 = -1 and since the answer is in the absolute value bars, -1's absolute value is 1, so the answer will be 1

but in a, only 8 is in the absolute value bars, not the complete answer
