Step-by-step explanation:

4(11+7)-9*8

PEMDAS or Order of Operations is the order that you solve problems:

P- Parenthesis  <--- First

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction  <--- Last

1) Start with the inside of the parenthesis (11+7) Because it comes first in PEMDAS:

4(18)-9*8

2) Next, multiply 4 and 18:

72-9*8

3) Next, multiply -9 and 8 together:

72-72

4) Subtract:

0
