STEP 1: Recall what is summation notation

http://www.columbia.edu/itc/sipa/math/summation.html

STEP 2:

The first term is 1

The second term is 2

The third term is 3

etc

Generally, the n'th term = n

and there are 10 terms, so n goes from 1 to 10 . This is expressed by the notation.


\sum_{n=1}^{10} n
