Question

At the beginning of the school year, the bookstore

had 130 copies of the third grade math book
By the end of the first month of school, all but
16 books were sold. How many math books were
sold during the first month of school?

Answer 1

114 books.

Explanation:

I'm pretty sure what you have to do is just subtract 16 from 130. (130-16).

When you do that you get 114 books. (sorry for basically no explanation.)
