Maths Bootcamp

The pq formula can be memorised without it ever becoming clear what it is actually the solution to. This bootcamp therefore starts from the parabola: first see what a quadratic function does, then calculate. Six levels lead from recognising the parabola through standard form and vertex form to the pq formula, on to factorising with Vieta's theorem and finally to problems where the equation has to be set up first. Every level holds four exercises, many of them step by step, so a mistake shows up early rather than only in the final answer. A thrown ball, an area to optimise and a profit function close the course.
