Welcome to Math! I’m PI, and I’ll be your guide around here. Multiply your number know-how by getting to know the mighty world of digits. Click on my friends to the left to meet them.

I'm ZERO,
I’m a bubbly fellow who will dissolve you to nothing. I have extraordinary powers.

I'm DIVIDE,
I’m here to split up the loot and make sure everyone gets equal portions of the pie. If there’s one of you, you can have the stash all to yourself, but if there’s more than one, you need me.

I'm MULTIPLY,
Divide’s opposite. Some people think I’m greedy, since I’m a big guy who hoards numbers together.

I'm VOLUME,
a funky rocker who can tell you the size of a 3-D object. Even better, I work hand in hand with capacity—how much of something another object will hold.
