Description

How many digits of pi can you remember? Since pi is an irrational number, the digits never end or repeat. You will probably never have to use more than a dozen digits in any calculation, so why learn the digits of pi? For some people this is a challenge. The Guinness record for remembered digits is 67,890 digits. With this program you will have the opportunity to test your memory, and learn a universal number. Have contests with your friends and family. This is a great learning tool for all ages. You be surprised how much you can remember with a little practice. The option to save the score will only appear if you do not make more than one mistake and do not use the hint or switch to the learn mode. Scores can be sorted by date, name, or score. Use this list to verify your retention over long periods.
