Estimate - Estimating Maths app for iPhone and iPad

Estimate - the estimating maths game for all ages. Play for practise or challenge the world in Game Center! Add, subtract or multiply combinations of 1s, 10s, and 100s with a choice of seconds-per-answer and lives-per-game. There is also an option to get double points if you answer in half the time given. The usual scoring system is 3 points for a correct answer, and 1 point for an answer which is within 10% of the correct answer, so you dont need the exact answer to score points. In no time youll be correctly estimating sums like 725 x 347, and youll be aided by seeing the actual answer after each question. Whatever your age, theres a setting for you.
