Re: New Theorem

LHS octal, RHS decimal or hexadecimal?
:confused:,what do you mean?

Oh you mean different number systems?Clever!

Since this is a chat room and this topic was nothing but a joke,I was just joking....


Here is the answer

Re: New Theorem

Nice, mathmaniac! (Giggle)

Here's mine : X can be cut down from the middle and separate the upper V and the lower V. Hence, X = 2 * V. Now, we see that it is an universal truth and consistent with any other mathematical axioms in Rome : 10 = 2 * 5 !

Let G be the group ({1,9,10},+) with the following addition table.

+1910
11019
91910
109101

Then $1+10=9. \qquad \blacksquare$

(Or alternatively, $G=\mathbb Z/2\mathbb Z$.)
