It demonstrates clearing algebraic fractions by multiplying through by 12, using factorisation and difference of two squares, and applying function notation with nested substitutions like f(g(1)) and f(g(34)). It also covers indices, including solving an equation like 4pi+n-2=-3, using the quadratic formula to three significant figures (for example yielding 1.27 from (4 plus or minus sqrt 76) over 10), and interpreting gradients from graphs in context (for every extra 1 kilometre across, 0.09 litres less are used). The session further includes proportion and inverse proportion set-ups and solving inequalities on coordinate graphs."}
