Math Rocks My World

I attended a Math Tutor Workshop this evening. I hate math, but this was kind of cool. I swear I never learned it in school. Try it, it really works!



To Multiply the 6's through the 10's

1. Hold out your two hands- name each finger:
-thumbs are 6's
-index fingers are 7's
-middle fingers are 8's
-ring fingers are 9's
-little fingers are 10's

2. To do a problem (let's try 7X8)
-stick out the fingers up to finger #7 on one hand (curl the remaining fingers on that hand in)
-stick out the fingers up to finger #8 on the other hand (curl the remaining fingers on that hand in).

3. Count the fingers sticking out by 10's. (In this problem you get 50 -10, 20, 30, 40, 50- so you know the answer is 50 something.

4. Count the number of fingers still down on one hand (3), Multiply this by the number of fingers still down on the other hand (2) (3x2=6)

5. You can either add that to 50 (56) or just use that as the second number of your answer for most of them (_6)

(Say it with a Jackie Gleason-like voice..."The Honeymooners")

Elaine just told me you did that. Awesome!
