is this right11+144-(-11)*12

155-(-11)*12

144*12

1,928

simplify -(8m)-(-7m+2)

15m-2

according to order of operation what should be done first when evaluating this expression do not solve [10-(-2+1)]-9

11 + 144 + 132

155 + 132

287

you should perform multiplication operation (the -11*12) first, not subtraction (not the 144-11).

-(8m) - (-7m + 2)

-8m + 7m - 2

-m - 2

you should distribute the negative sign to the terms inside the parenthesis. thus their sign change to its opposite (the -7m becomes +7m and +2 becomes -2)

for the third question, the first operation you must do is to simplify the terms inside the parenthesis. recall PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

hope this helps~ :)
