Another little tool: something I made a while ago. When I swapped servers it had disappeared from the web, now it will have a definitive spot here. It’s a fractions calculator that shows all the intermediate steps that I built for my kids when they were first doing fractional calculus in school. Pressing the equals sign will provide a short howto.

so you taught your kids that 2 1/0 == 2 ?? sacrilege!

Leuk! I like the explanatory route.
