Root Explanation

Combinatorics is formed from "com-" (meaning together) and "binare" (from Latin, meaning to pair or to double). The word refers to the branch of mathematics dealing with combinations of objects in specific sets under certain constraints.

Memory Tip

Think of 'together' ('com-') and 'pairing' ('binare') to remember that combinatorics is all about the ways to combine or arrange things.
