Pi is the most studied number in mathematics. Pi is an irrational number and, by definition, it is the ratio of the circumference of a circle to its diameter. In other words, Pi equals the circumference divided by the diameter. It does not matter how big or small the circle is, Pi remains the same. Pi is often written using the symbol π and is pronounced "pie", just like the dessert.
