3. 2520 is the smallest number divisible by the numbers 1 through 10.
4. You can remember the value of Pi (3.1415926) by counting each word's letters in 'May I have a large container of coffee'.

My favorite mnemonic for remembering the first 20 decimals of pi is
ReplyDeleteHow I wish I could enumerate pi easily, since all these bullshit mnemonics prevent recalling any of pi's sequence more simply.
that's amazing. I will add this mnemonic in next post
