Let’s continue our math tricks mnemonics memory technique to remember numbers with the codes for the numbers 4, 5, and 6.  Again, these memory aides should be practiced so that your brain becomes “hard-wired” for coding and un-coding your words and phrases.

The number “4” is coded as “r”.  The memory technique to use here is to remember that the word “four” ends in an “r”.

The number “5” is coded as “l”.  I have seen several techniques that can be used to remember this code.  First, the Roman numeral “L” means “50”.  Also, you can remember that your thumb and index finger together looks like the letter “L” when you spread out all the digits on your hand to indicate “5”.

We will finish this part with the number “6”, which is a little more challenging in that it has several codes.  “6” can be represented by a “j”, or a “sh”, or a “ch”.  For the letter “j”, you can remember that a mirror-image cursive “j” kind of looks like a “6”.  For the “sh”, you can remember that “shix” sounds like “six”.  Also, “chix” rhymes with “6”.

If you have any other ideas or suggestions for other memory aides for these codes, please feel free to let us know by posting a message!

This technique and other math tricks are covered in detail in the book “Secrets of Mental Math“.
