I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
This is really obvious but the answer is 4 feet.
It should be 30.4
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.
I hope this helps!
