Number & Algebra

This section of the eBook is all about the Number & Algebra unit. Here you can read, learn and practice all the sub topics.There are 3 main themes to the topics in this section. First, an emphasis on numbers and notation as tools. With indices, standard form, logarithms, accuracy and percentage error we focus on describing and presenting quantities. Then, with the sequences we look at the idea of relationships and growth before applying these in the context of financial mathematics.
