Write an expression for the sequence of operations described below. add 9 and 6, divide r by the result, then subtract what you have from q Do not simplify any part of the expression.

Answer 1

r / (9 + 6) is the result of dividing r by the sum of 9 and 6. But that result is to subtracted from q.

q - r/(9+6)

An extension to this problem might ask what is the value of this expression if q = 45 and r = 30?

45 - 30/(9+6)

45 - 30/15

45 - 2

43
