Description

Numbers and number patterns are the basic building blocks of algebra and arithmetic. And we cannot escape using numbers in our everyday lives. We use count through the minutes and hours of our day with our clocks. We count out cash to pay bills and take a flutter on the lotto by choosing our numbers.

Applying Arithmetic and Geometric series in finance is examined through investments and loan repayments. Using AER (annual equivalent rate) and APR (annual percentage rate) when calculating your repayments is examined. Students then look at the concept of a complex number. They are shown how to multiply, divide, add and subtract complex numbers.

Complex numbers can be used to represent the current flow in a circuit and they are widely seen in electronics generally. Numbers are used to measure the perimeter and area of many shapes (hexagons, rectangles, triangles and circles) and we also try to work out the volumes of solids such as cones, spheres, cylinders and hemi-spheres.
