Wikijunior:What can you use math for?

About the book

Welcome to the Wikijunior "What can you use math for?" project.

Our society is in need of people who know math. A big motivation for learning math in the first place is to have some idea of what it can be used for. This is an attempt at catching children early on, and giving them some ideas of what math can be used for: both now, and later in life.

Please add any article that you think will spark interest instead of quelling it. Thanks.
