What Does "Simplify" Mean?

Imagine your pencil case has 3 red pens and 2 blue pens, then someone gives you 4 more red pens and takes 1 blue pen. You wouldn't say "I have 3 red + 2 blue + 4 red − 1 blue" - you'd say "7 red and 1 blue"! Simplifying is just combining things that are the same type. In algebra, "3x + 2y + 4x − y" becomes "7x + y".
