■ WHAT YOU CAN DO WITH MATHTRE
[5 calculation modes]
Addition, subtraction, multiplication, and division, plus Sums, where you add up a series of numbers one after another. From basic arithmetic drills to abacus-style running totals, it's all in one app.
[Difficulty from 1 to 5 digits]
Set anywhere from 1 to 5 digits, and choose the digits for each number separately (for example, 2-digit × 1-digit). Start with easy warm-ups and work your way up to big numbers that challenge even seasoned mental math fans. You can also choose the number of questions and, in Sums mode, how many numbers to add.
[Fresh problems every time]
Problems are randomly generated for every session, so there's no memorizing the answers. Every round is a true test of your calculation skills.
[Track your time, see your progress]
MathTre automatically records your clear time and your time per question. Beat your best and you'll see "New Record!!" — nothing motivates quite like beating yesterday's you. Your total correct answers and play time are saved too, so you can always look back on how far you've come.
[A daily brain workout]
A session takes just a few minutes. Do a set with your morning coffee or one before bed; it fits easily into any routine. A little practice every day is the surest way to get better at mental math.
[Simple and focused]
Large, easy-to-read numbers on a clean screen keep you focused on the problem in front of you. Customize the theme and sound to suit your style. Works on both iPhone and iPad.
