Number Sets
Each number set contains the number set before it:
- N: Natural Numbers - ie all whole numbers - 0,1,2... onwards
- Z: Integers - ie all N plus negative integers - -2,-1,0,1,2...
- D: Decimals - ie all Z plus fractions that
- Q: Rationals - ie
- R: Reals - ie all Q plus the irrationals, which are decimals that neither terminate nor recurr
