Theorem 1
Area of circle = /4 x area of square
When I was in bed one night I started thinking about circles and squares, and then I suddenly

Theorem 2

1/n - 1/(n+1) = 1/(n2 + n)

One day I was in the car and Mummy was asking me a question about fractions when I realised that
when you start with 1 over a number and take away 1 over the number + 1, the denominator on the
