Assuming we don't have a calculator that can do summation notation. My class is not up to summation yet, but I'm asking a question involving this concept because I'm not all that experienced using it. My calculator can do summation but that's because I programmed it to. But when we actually catch up to this concept, are we to calculate it by hand?
Take, for example:
$\displaystyle \sum_{i = 0}^3 2i + 1$
Do you think they will tell us for the $4$ values of $i$ (from $0$ to $3$), do the following operation, or is there some other faster way of doing it?
Sorry if this is a silly question, this has just been on my mind...
