Maths: mental maths practice

Mental maths in 34 levels, from 3 + 4 to multiplying and dividing big numbers in your head. Each level is a short set of questions to answer from memory, and every miss shows the right answer and how to work it out. Levels open one after another, and a boss level checks each stage.
