# Mathematics beyond age 16

Mathematics post-16 brings together and extends the range of mathematical ideas students encountered earlier on in their mathematical career (the ideas presented on the other sections of this website).

New mathematical ideas at post-16 include trigonometric functions, calculus, and statistical inference. These topics are among those at the heart of what is sometimes called ‘higher’ or ‘senior’ mathematics (that in turn leads on to more ‘advanced’ or ‘formal’ mathematics).

Across these three areas, there are ideas of mathematical modelling that bring together concepts of algebra and functions, proportionality, measure (especially compound measure), and sophisticated forms of reasoning about data. Beyond this there are the myriad uses made of mathematics in the workplace, such as in engineering, in business and finance, and in design.
