Abstract
The initial idea of "number" leads quickly to the need to represent numbers and then manipulate numbers. We emphasise the representation as the terms of polynomial in some base and especially "binary numbers" (to base 2) and "decimal numbers" (to base 10). This leads into conversion between bases and the representation of fractions in binary.
Keywords: Polynomial Representation, Binary, octal and hexadecimal representations, base conversion by arithmetic, base conversion by table lookup.
