Example of an algorithm that adds up integer numbers consecutively. Really shows how maths rules can speed things up. If you were to add 1 + 2 = 3 and then add this answer to the next number (+3) all the way to 1000000 in a loop, this would take considerably longer. In my example you can change the end number to what ever integer you like. I did some number key code checking. Enjoy.

? I still don't get what the point is.

Did you know summing all of the integers from 1 to N is the same thing as ( N x ( N+1 ) ) / 2?

And, if you square a number which ends in 5, you can multiply the rest of the number x N+1 and append 25? e.g. 65^2 => 4225,and 55^2 => 3025.)
