Follow P.E.M.D.A.S. (Parenthesees, Exponents, Multiplication, Division, Addition, Subtraction). Be sure to add, subtract, and all that jazz left to right!

Equation? 6 (-3) + 2 - 5

1) NO Parenthesees

2) NO Exponents

3) Multiply 6 (-3) = -18; -18 + 2 - 5

4) NO Division

5) Add -18 + 2 = -16; -16 - 5

6) Subtract -16 - 5 = -21

Following P.E.M.D.A.S, we get an answer of -21.
