Algebra in Key Stage 3 is mostly *generalized arithmetic*,
offering an explanation for the way that relations and operations between
particular numbers form patterns. The idea of a mathematical 'proof' starts to
emerge as students look at the *structure* of a situation, rather than
simply *more* examples.

Algebra is also a useful tool in *geometry*, where
the relationship between the various components of the physical situation can
often be described using formulae - angle rules and Pythagoras, for example.

The utility of Algebra lies partly in how it can give one
a *starting point* from which to tackle a problem, while the joy of Algebra
lies in the* final* exclamation of "so *that's* why it works"
!

This joy is a very special attribute of Mathematics, and one which we hope many students will appreciate for the first time at Key Stage 3.

So let's see about a few 'pretty' problems.
