Math Mojo is here for you to learn math in new ways. It was created by a professional magician (me, Professor Homunculus) who believes that anything can be done differently, and usually better, than it is normally done.

The basic component of Math Mojo is speedmath. Although there are lots of basic lessons on things you will find interesting here, the main thrust will be on interactive lessons and instructional booklets which teach you speedmath methods.

There are different types of speedmath, and I have explored many of them and distilled some of them into Math Mojo, and other methods I have created myself. All of them will be explained in plain English, and you will need no prior knowledge of anything beyond the most basic addition and subtractions skills to begin learning Math Mojo.

At this time, the only interactive lessons are on

Check out those lessons to see what the interactive lessons will be like. You can also learn left-to-right subtraction in the abax lessons, if the interactive lessons don't do the trick for you.

Check out the Interesting Lessons page. You will be suprised at how many things you (and almost everybody) are not 100% clear on. Fill in your mathematical gaps here! Almost all of the lessons in Math Mojo are listed here.

The pages which I recommend most for beginning learners are those on the abax. Start with "Introducing the Abacus" and take it from there.

Stuff you should Know
(This can be used as part of any educational curriculum)

This section is not necessarily math-related. Here you'll find interesting things about current events, general knowledge, and more. It's my way of helping myself learn new stuff and remind me what's important.

Everyone seems to have his/her opinion about "what is going on" in the Middle East. But do they even know where it is? An informed public is a safer public. Are you informed?

Find out what you and others know (or don't know) about Middle East geography
