In a short answer, to find average you need to add it all up and divide by the number of things you added. Ex. say I want to find the average for my english class, my grades are 90, 98, 100, 87, and 70. I would start by adding them up to get 445. then since i have 5 grades, i would divide the sum 445 by 5 and get an 89 as my average.
(Everything in this answer is example only, not my real grades.)
