The sum of the first 100 numbers is 5050.
There is a formula to do this, which was discovered by Carl F Gauss.
S = ( N * ( N +1 ) ) / 2
so in this case:
S = (100 * 101) / 2
S = 10100 / 2
S = 5050

The sum of the squares of the first 100 natural numbers [1..100] is 338350, while the sum of the first 100 natural numbers squared is 25502500.
This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.
