Factorising — type an expression to break into factors, then press Factorise.
Try: x^2 + 5x + 6  or  6x^2 + 9x
i
Expanding brackets — type an expression to multiply out, then press Expand.
Try: (x + 2)(x + 3)  or  3(2x + 1)
i
Simultaneous equations — enter two equations (each using x and y), then press Solve.
Try: 2x + 3y = 13  and  x - y = -1
i
Function evaluator — define f(x) using x, then either find f(x) at a specific value, or find x when f(x) equals something.
Try f(x) = x^2 + 2x + 1
