I went on the maths competition today, and there was an awesome task that went something like this:
You can only fill each letter with one positive normal number(1,2,3,4,5...), and circle of which the number can you get from the following:
So, same letters mean the same number and you can only use each same number only once(ie. If you decide to give K=1, that means no other letter can be 1)
I hope you understand it^^, enjoy solving this interesting 'puzzle'.
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
