1. For number 14, less than is a turn around word, so that means it goes at the end of the expression.

2. 4 times a number means multiplication, so you put that at the start. A number would equal n.

3. Your answer is 4 × n - 8.

1. For number 15, 8 decreased by is not a turn around word, so do not put it at the end.

2. 4 times a number, same thing as number 14 except PUT IT AT THE END.
