I came accross this little math problem in a new biography of Lewis Carroll. It was on a math final during the 1850's at Oxford University. I believe that any budding mathematician in the 9th grade should be able to figure it out.
Problem: Let m and n be arbitrary odd integers (m>n). Prove m^2 -n^2 is divisible by 8
