Answer:
32
Step-by-step explanation:
We are given the expression:
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
Next, multiply -8 and -24.
⇒ -8*-24= 192
Finally. divide 192 by 6.
⇒ 192/6 = 32
When evaluated, the expression -8(13-37)/6 is equal to 32.
