expansion question

How would this expression be expanded... 12+q(3p-5)

Since 12+q must happen before the multiplication of the expression in parenthisis, i don't see how it can be expanded

thanks

Actually, the order of operations specifies that the multiplication by the q must happen before the addition to the 12. :D

remember BODMAS for precedence

brackets
p(o)wers
division and multiplication
addition and subtraction

12+q(3p-5)

12 + q x 3p - q x 5

12 + 3pq - 5q
