In school we learn about numbers, connections between numbers, and how to manipulate them to solve problems — that’s arithmetic and algebra. At the same time we learn about shapes and space, shapes being made from straight and curved lines — that’s geometry. Then at some future stage (earlier rather than later according to current trends) these two major threads are woven together with the realisation that equations can describe lines — and we have coordinate geometry. How’s that for a whirlwind summary?
