How many mental arithmetic questions can you get right in a minute? This simple program generates random questions on a variety of topics ranging from addition of 2 single digit numbers through multiplication tables, percentages, decimals and on to fractional indices. The difficulty of the questions depends upon which of the 50 levels you decide to tackle. A clever weighting system gives you a final score depending upon the level attempted and the age and ability group that you are in. The higher the level of difficulty, the higher your score could be.
