Answer:
20
Step-by-step explanation:
Any work inside parentheses must be done before anything else.
Here 13 − 2(1 − 15) ÷ 4 involves 1 - 15 inside parentheses. The given equation simplifies to:
13 − 2(− 14) ÷ 4.
Performing the indicated multiplication:
13 + 28 / 4
Multiplication and division must be done before addition or subtraction.
Thus, we have 13 + 7
The final value of this expression is therefore 20.
