Math Tricks – How to Remember Pi

What is pi?  Can’t remember pi beyond 3.14?  That’s OK. because there are math tricks to help you remember.  My favorite is this mnemonic:

“How I need a drink, alcoholic of course, after the heavy lectures involving quantum mechanics.”

Each word contains the number of letters for the digit that belongs in that word’s place.  For instance, replace “How” with “3”, “I” with “1”, etc.

Using this math trick, we get:

3.14159265358979

Of course, you can make up your own mnemonic; if you do, please post your ideas here!

Mnemonics as a Numbers Memory Aid – Part 5

September 28th, 2009 by Math Tricks | 1 Comment | Filed in Remember Numbers




Here we will conclude our memory technique to remember numbers with the codes for the numbers 7, 8, 9, and 0.

First, “7” can be coded as a “g” or a “k”.  To remember the “g” code for 7, simply remember that “g” is the seventh letter of the alphabet.  The “k” code for 7 can be remembered like this.  Visualize uppercase “K” as two sevens back to back (one 7 being the mirror-image of the other) and turned 90 degrees anticlockwise.

Next, “8” is coded as an “f” or a “v”.  The “f” code can be remembering that a cursive lowercase “f” resembles the number 8.  For the “v” code, I like to remember the old vegetable drink commercial line, “”WOW! I could have had a V8!”

The number “9”, as we have seen before, can be coded as a “b” or a “p”.  Remember that lowercase “b” looks like an upside-down 9, and “p” looks like the mirror image of the number 9.

Finally, the number “0” is coded by the letter “z”.  Any guesses as to how to remember this one?  RIGHT!  The word “zero” begins with the letter “z”.

Once again, if you want more in-depth information on this memory technique and other math tricks, then I recommend the book “Secrets of Mental Math”.
