Price: £0.59

Do you remember the Hewlett Packard HP-15C Scientific Calculator? It was the most advanced calculator in the Eighties, and as well as being programmable, it had built-in support for complex numbers, matrix mathematics, numeric integration and root solving. Fast-forward 25 years or so, and how things have changed. Virtual on-screen calculators are the norm, and every functional PDA or smartphone will include one. This full-blown scientific calculator includes support for formula entry and is the ideal tool for rendering formulae in 2D or 3D. Other features include a polynomial function and slides to change the maximum and minimum of X and Y values dynamically. If you need help working on advanced algebra problems, then look no further.
