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!

Cool beans, Marcus!
Take the 2nd odd number, 3. Since ’3′ is number ’2′ meaning 2nd, take the ’2′ and double/square it, leaving a 4. Put a space between the four and 3, then find the difference between 3 and 4. The difference will be the center number. Then divide by 100. 3_4 > 4-3=1 314 314/100=3.14
