Example: ∑ n = 1 5 n = 1 + 2 + 3 + 4 + 5 = 15 . Beneath the sigma is the index (in this case n ) which tells us what value to plug in first. Above the sigma is ...

In mathematics, it represents "the sum of all terms." When we see the symbol ∑ , it means that we''re being asked to "sum up" a sequence.
