It called Sigma and using it means to sum the numbers between (inclusive)
the top and bottom number. Often one of the number is "n" which is just a
generic variable. Using it is typically called Sigma Notation and is often
used in series calculations.

Summation notation (sigma notation) with the function listed to the right running
within a range/limit usually listed below the
sigma, but sometimes beginning with the limit below the symbol to the limit above.
In a nutshell.
