Math Quirk
 
This is old, but still quirky (to non-mathematical me anyway):

1) Pick a number, 1 through 9

2) Multiply by 3

3) Add 3

4) Multiply by 3 again

5) You'll get a 2 or 3 digit number

6) Add the digits of that number

What number do you get?

9 every time, I wonder why.

I know--I know--I know! Gee, I must have had a good 6th grade math teacher...back in the 1950's.
