    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.

    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
