Question

how would you solve this problem? i'm trying to learn for my PERT test. :)
9 ∙ 9 - 8 ∙ 3 + (-30)

anonymous · Answer

I would do pemdas (Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction). Except, cross out the ones that aren't there. So I would MAS, which is Multiplication, Addition and subtraction. So for example, 9*9=81 

81-8= 73

73*3= 219

219+(-30)= 189    Hopefully this helped.

I would e-mail a math teacher than and have them go over some of the problems with you and give you some example ones to figure it out. But that is a trick question though. :\
