\[\sum_{k=5}^{10}\]is a good place to start

then this might take a bit. It is simple enough tho. the symbol: \(\sum\) is a greek letter for "S" and indicated that we are going to be adding up stuff

the number on the bottom tells us where we start at; and the number on top tells us where we end at: in this case we start with k=5 and end with k=10

i like to write it out to begin with like this: k : rule  5 : 5k = 5(5) = 25 6 : 5k = 5(6) = 30 7 : 5k = 5(7) = 35 8 : 5k = 5(8) = 40 9 : 5k = 5(9) = 45 10: 5k = 5(10)= 50 does this make sense so far?

\[\sum_{First}^{Last}(rule)\] using the rule, and stepping thru the numbers from first to last, we can generate all the numbers that are needed to be added up.
