Really confused. I'm a online student and the instructor taught us how to do this but she didn't use these type of equations so I'm really lost.
$\displaystyle -4 (3-7) + 2^2 (-6)$
-3 + 3 (5-12)
6 + =

Do the parentheses first. Then perform the multiplications. Lastly, add orr subtract.
I'll do the first for you.
1. Parentheses
$\displaystyle -4(-4)+22(-6)$ because $\displaystyle 3-7=-4$
2. Multiply
$\displaystyle +16-132$ because a negative times a negative gives a positive.
4. Add/Subtract
$\displaystyle -116$
Have you ever heard of P.E.M.D.A.S.?
