With a grown-up's help, Nico agrees to do a small job for a neighbor. He earns $8. The supplies he needs cost $3.

Nico writes both amounts down. He has $8 − $3 = $5 left.

“Why not just write eight?” his friend asks.

“Because my wallet noticed the three.”

An expense is a cost you pay. Keeping track of expenses helps Nico see what the job actually leaves him.

Before taking a job, check with a grown-up that it's safe and allowed. Find out what supplies it needs, too.
