Next time you feel awful about maths--remember that you solved one of the 'outstanding open problem' while you were just 17.
I was bored in class today so I worked out the first 150 numbers in the Fibonacci sequence without a calculator.
In case you're wondering, it's 9,969,216,677,189,303,386,214,405,760,200.
