Pi itself is a very interesting number. It occurs in many areas of mathematics, including calculus, geometry and simply arithmetic. Pi is an irrational number, that is it cannot be written down in its whole form. It has an infinite amount of decimal places after the original 3. It can be used to calculate the area or circumference of a circle. Area of a circle = pi*r^2, and the circumference of a circle = 2*pi*r, where r is the radius of the circle. Another interesting factoid is that e^(i*pi) = -1, where e is the natural number and i is the square root of -1.
