Another wonder example of the Beauty of Mathematics

9 x 9 + 7 = 88

98 x 9 + 6 = 888

987 x 9 + 5 = 8888

9876 x 9 + 4 = 88888

98765 x 9 + 3 = 888888

987654 x 9 + 2 = 8888888

9876543 x 9 + 1 = 88888888

98765432 x 9 + 0 = 888888888

Brillant, isn't it?

Okay, You lost me after the first 88 sum! LOL! Math has never been one of my strong suits! :) Great post below on the orphanage. I have a cousin in Tanzania, serving as a "missionary/layworker" in a childrens home. Oh, and the 1# weight gain isn't too bad...just a bump in the road. At least it was gained on good food and not bad! :)

Thanks for your encouragement over at my blog! ~hugs, Rhonda :)

Those are brilliant. The best I can do with math is knowing when multiplying your nines, the sum, when added together always equal 9.
For instance 9x5=45 then 4+5=9.

I am with Brenda my best stops at 9 too.
The sum 9
and the answers go 0,1,2,3 down and 0,1,2,3 up.

What I want to know is who sits and think these up. Most people have seen 1-10 times 1-10.
But who has seen the log numbers written down to figure this!
