Homework Statement
I'm trying to wrap my head around series notation, but I'm finding some of the transformations hard to grasp. For example, this one:
Homework Equations
[itex]\Sigma^{n}_{i=1} (2a_{i}-3) = 2\Sigma^{n}_{i=1}a{_i}(-3n)[/itex]
The Attempt at a Solution
In the above expression, I don't understand how you end up with -3n on the RHS. Why can't it just be left as -3?
