These exercises use MathQuill, a web formula editor designed to make typing Maths easy and beautiful. Watch the animation below to see how common mathematical notation can be created using your keyboard.
Use ^ for index/exponent
Use _ for the base of a logarithm
Use space and tab to get down from the index position or up from the subscript position
No brackets required for the log function - write log10 rather than log(10)
