Speed math trainer

  1. Jul 10, 2007 #1
    I've found this flash speed math trainer.

    I was wondering if anyone knows of a math trainer for addition that helps you add up a list of numbers fast in your head.

    I saw some program that flashed numbers in quick succession 5..3..9..3..3
    and then timed how long it took you to type the answer. You could set the number of questions, the increment between flashed number, etc. The next level was to move on to 2 digit numbers.

    Has anyone seen anything like that?
