Question

What is the expression for "the difference between five times a number and twice that number"?

5(2 - N)
5N - 2N
2N - 5N

Answer 1

you can eliminate choice #1 because nowhere in the question does it say "the difference between two and a number"

so now it's between #2 and #3 with the only difference being the order of the two terms.

since "five times a number" comes before "twice that number" in the question, 5N will come before 2N in the expression.
