Root Explanation

Subtraction is formed from "sub-" (meaning under or below) and "tractio" (from "tractus", meaning to draw or pull). The word describes the process of drawing away or taking away a quantity from another.

Memory Tip

Think of 'drawing away' ('tractio') something 'under' ('sub-') — that's why subtraction means taking away.
