Solution to the make up four puzzle

A virtual star to Mr. B. on solving the puzzle. Remember, the idea is to move only one stick to make the equation correct:

Starting postions: | + || + ||| = 4

(move one of || to make a "+" with the middle stick in |||)

I have made a little Flash animation to demonstrate it, but I can't figure out how to upload this to Blogger. If you know, please advise.

Elias.

Bek came from the name of the location, the Bekaa valley. The Romans then transformed it into the largest temple dedicated t

Book Review: The Math(s) Fix - Part 1 of 2

The Math(s) Fix is Conrad Wolfram's case for teaching mathematics with the assumption that computers exist! To be clear from the beginning, Wolfram is not advocating that we solve the same problems but with a greater reliance on computers and calculators. He wants us to recognise that computers have revolutionised the discipline of mathematics and that we need to reflect this change in our curricula. In the following lines, I will present a summary of Wolfram's thesis, as I understand it. My aim is to give you enough of an idea so you can decide whether you want to read the book for yourself. This part will concentrate on the case that the book builds for a radical change of the maths curriculum. Part 2 will explain the alternative in more detail.
