Answer 1

Generally speaking, summation can be done through three standard methods:

• initializing the result to 0, and looping over all of the possibilities, adding each term to the result
• using sum()
• using symsum() if you have access to the symbolic toolbox. This should be used only for formula and not for specific numeric values.
