A second series of 12 programmes aimed at giving direct help to those having difficulty with O-level maths. 3: Indices
Most of us can accept that -4 has a clear meaning, but when we see the same —4 written as an index it takes on a strangely unreal air. Yet indices arise out of a simplification, a shorthand way of writing down multiplication. It is this new way of putting down the mathematics that is unfamiliar, not its implications.
