Speed up your mental arithmetic
The purpose of these "virtual flashcards" is to help you build
up your speed at mental arithmetic so you don't have to turn to the
calculator every time you need a little sum or product. I know it is a
bit ironic to use a computer to eliminate the dependence on a calculator.
Sometimes irony is neat.
Start with Addition - Level 1 - to get used to
using the applet. Go for speed. The current record for a perfect
10 correct is seconds on this first applet.
Please send me your comments or suggestions on these drill pages
