is there a formula to solve a long series of addition of say 18 through 10748(adsbygoogle = window.adsbygoogle || []).push({});

instead of doing the tedious summing of 18+19+20+...+10748

there probably is but i found a formula yesterday and I want see if it is the same

how about multiplication - is there an easy way of computing 97! (factorial)

instead of using a computer or multiplying 1*2*3*4...*97
