Sums
What is a partial sum?? Can someone explain that to me? Also, how do u do a summation on your calculator. And can someone briefly sum up what happened on Tuesday because I missed most of block. Thanks.

a partial sum is the sum of all the answers to that equation up to that number..... for example....if it asks for the third partial sum of n^2-5n+2, you would do [1^2-5*1+2] + [2^2-5*2+2] + [3^2-5*3+2] = -2+-4+-4=-10
i hope that helps
