Working on updating Flash to JavaScript (a very large project indeed).

Here is the new JavaScript version of the Math Trainer: Math Trainer - Addition

The old (but still good) Flash version: Math Trainer - Multiplication

You can make the "Addition" version work on Multiplication by clicking the "Multiply" tab at top.

What do you think of the JavaScript version?

Happy Easter to all.
