## About Me

I love maths! I have participated in quite a few competitions organised by the UKMT (for more on this, click here). I like making problems, particularly difficult ones. Have a look around; I have uploaded various bits and bobs of documents, websites and general maths projects that I have created.## My Maths Websites

**06-08-2014**I found this problem's solution so ingenious that I have posted it here. I am unsure of the source, but I remember that it was in a high-level competition.

Problem 1:A 4 by 4 square has its opposite corners cut off so that in total, one unit square is removed (see diagram). Show how to make one cut to form two pieces which can be rearranged to make a 3 by 5 rectangle. (see solution)
