## TOM's MONEY MATH PROBLEMS

Tom is up to his ears in debt - and needs to learn about money math to get himself out of trouble. See how he figured the math behind the money in Money Math.

## THIS MONTH'S MATH TIP

For each new math topic, try the following so you understand - and remember - the topic better:

a) DRAW what is going on (a diagram, a graph, a flow chart)

b) WRITE the conditions for it to work (eg 'x must be positive' or 'c must be constant')

c) CHECK your answers! Most equations can be checked by substituting your answer in the original equation. Does it work?

## LATEST FROM THE MATH BLOG:

1) THE MATHS OF MUSIC

I have always been interested in the close connection between math and music.

2) LEARNING MATH VIA A BLOG AND A WIKI

I came across a calculus blog where the contributions are made by the math class. They also have a wiki for sharing solutions to math problems.

3) MATH ILLITERACY

A funny math T-shirt company...

4) NEWTON'S LAWS REVISITED

Here are some laws which Newton may have written if he was alive today...

5) WHEN AM I GONNA USE THIS STUFF?

The Regional Applied Math Project (RAMP) gets math teachers to work in the "real world" for 40 hours and write up their observations on how mathematics is used in the workplace.
