Two less than the product of 9 and a number

9 x n - 2

to do this, think in this way:

two less than (the product of 9 and a number) is the same thing as saying

(the product of nine and a number n ) subtracted by two

you could also represent this as:

(-2) + (9 x n)

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
