Just rember that adding and substracting is what you do last.
Example: So for your above question you should do -9x6 first...write down that answer. Then do 7 x -3 wrtie down the answer...and then when you have both answers written down add them youll have -54 + -21 . Now i know it looks weird to have a plus sign there. But its the same as -54-21. Good luck

PEMDAS
-9 x 6 = -54
7 x -3 = -21
-54 + -21 = -75

Oh my! If the subject actual reads 8+12 on suitable of the divider line with (-3)(-11) under the line, then the respond is going to be 20/33. in spite of the shown fact that, despite if it rather is 8+ 12/-3 -11 then the respond is -7. technique the Parentheses first. (Please) Then the Exponents. (Excuse) Then Multiplication. (My) Then branch. (expensive) Then Addition. (Aunt) ultimately Subtraction. (Sally)
