"The probable is what usually happens." — Aristotle. What many people refer to as 'good luck' can actually be explained by a little knowledge about probability and statistics. Our dice game allows you to see how increasing or decreasing the number of dice rolls affects an outcome. So give it a try, choose the number of rolls you would like to make... ...and roll the dice!nrich.maths.org :: Mathematics Enrichment :: Monthly Index page:: All Stages
This article introduces the idea of generic proof for younger children and illustrates how one example can offer a proof of a general result through unpacking its underlying structure.
Public Beta Preview This website is currently in the late stages of its development, a state referred to as beta . As with all beta software, it has some quirks and many parts are not yet available. We are working hard to finalize the system's structure, and roughly once every two weeks we roll out new functionality towards this goal. Until then you may notice that some resources move or even disappear for a while.

What did people do to save time working out more difficult problems before the calculator existed? The illustration shows the graphs of fifteen functions. Two of them have equations y=x^2 and y=-(x-4)^2. Find the equations of all the other graphs.
