Explained well Trevor!

This was simple enough I could explain it to my 10 yr-old and his
pre-algebra friends...

...AFTER I amazed them with the trick.

And I've updated your Registry entry if you want to check it for me.
Or if you have any details you would like to include on the Photo & Details
page:

Very nice looking car.  I'm glad to hear you are back on the road.
Have you set the rev limiter to something below 9,000 RPM?

You may want to add a closer image of the new motor
(...and add the VIN and front trunk shot for completeness.)

The proof is fairly simple
 
any two digit number can be expressed as (10X + Y) where X, Y are elements
of the set (0-9)
 
adding the two digits together gives you (X + Y)
 
so     (10X + Y) -  ( X + Y)  =     10X + Y - X - Y
 
which = 10X - X + Y - Y
 
which = 10X - X + 0
 
which =  9X + 0
 
which = 9X 
 
hence all are divisible by 9
 
 
Inerestingly is works for three digit numbers as well....briefly
 
100X + 10Y + Z - X - Y - Z = 99X + 9Y = 9 ( 11X + Y) = hence divisible by 9
 
Oh
 
and it works for 4 digit numbers ....5 digit numbers..
 
the proofs remain elemental as previously describe...
 
I leave the proof for all positive integers greater than or equal to 10 to
the reader.....
 
 
Trevor "IL CONTE" and back on the road again...
