10+10 = 2 x 11 is a "true" statement.
How come?

Some Thoughts re(2): Base 0 | Comment 10 of 15 |
(In reply to re: Base 0 by Steve Herman)

Absolutely true.

a^0 is 1 for all a , except a=0.

The reason for this definition is to g

comply with the formula a^m / a^n = a^(m-n) .

when m=n   a^m / a^m = a^(m-m) =a^0

but a^m / a^m =1   for any a , safe a=0 .   0/0 is undefined.

 

NB What about the puzzle ? It is in the trick section , not math!!
