Hint: When entering mathematical expressions in the math boxes below (f(x), g(x) and h(x)), use the space key to step out of fractions, powers, etc. On Android, begin entry by pressing Enter.

Type simple mathematical expressions and equations as you would normally enter these: for example, "x^2[space]-4x+3", and "2/3[space]".
