Algebra: Real Numbers

Want to put in a little extra time identifying your different number types? Click here for some practice lessons, and if you have any questions, you can email a tutor. Your tutor, at least, is guaranteed to be rational.

Function Machine

This is great for honing your pattern-spotting skills. Input numbers in the function machine, see which numbers come out, and try to determine the pattern. If you get "paisley," you’re doing it wrong.

### Videos

Types of Real Numbers

More of a visual learner? No problem. Here’s a video that uses Photoshop and a pretty green drawing tool to illustrate the different number types (will also be available in mauve and cyan in Spring 2016).

Negative Exponents

Exponents got you down? Let this instructional guide help you lift them back up to where they’re supposed to be.

### Games

Crack Hacker’s Safe

This game is another good tool for helping you find patterns—not only in numbers, but in colors and shapes as well. (Okay, so that part is a little second grade, but at least it isn't drab and boring.)

Mystery Picture

Solve the problems correctly and uncover parts of a picture. When you're done, you can print it out, frame it, and hang it on your wall. Or not.

The Factor Game

This is a two-player game to help you practice factoring, so we hope you have a friend around who can play it with you. Or a mom. Or a pretty sharp Pomeranian.
