Projects / QMentat


QMentat helps you practice mental arithmetic. It uses arbitrary-length fixed point arithmetic, and can handle any size numbers, only limited by the size of your screen (and in the case of division with an integer result, the speed at which the number can be factored). It is also quite configurable, allowing you to tailor the questions to your needs.

    Release Notes: This release fixed bugs and added a Windows version. A crash if unexpected characters end up in the answer input text was fixed. The random number generator is no longer seeded every time a random number is requested. A few issues were fixed to make the program build on Windows using MPIR.

      Release Notes: This release includes addition, subtraction, multiplication, division, powers and roots. All can be done with arbitrarily large numbers, except integer division (which is limited by the time taken to factor). All this in a nice Qt GUI.
