Roman matches (Posted on 2010-09-28) Difficulty: 1 of 5
My friend placed on my desk 10 regular matches, forming the following "equation":


XI+I=X


After I've pointed out to him that it is not true, he responded:
"Well, then make it true, but touching neither the matches nor the table.
No adding , removing, burning etc - just make it e q u a l ! "

How would you solve it , obeying all his rules?

Just view the matches from the other side of the desk, then you have X = I + IX. (What about those ABAC sayings, Ady?)
