Sequential/continuous/continued/parallel addition [closed]

I would like to know what's the standard way to say sequential/continuous/continued/parallel multiplication or addition for calculation like 3 * 5 * 10 * 2 * 11 and 1 + 5 + 3 + 2 + 4 + 100.

PS: Glad that this question attracts some attention. I asked because in Chinese there are effectively specific names: 连加 and 连乘 where 连 means this, 加 means addition and 乘 means mutiplication.

Such calculations don't have a specific name. They are merely products or sums (respectively). The answers which suggest, for example, that you refer to the sum as a series are incorrect, as the relevant feature to create a series appears to be missing. You would need to identify a relationship between elements of the series, specifically a way to calculate each successive element, and the sequence of values (typically integers) over which to perform the calculation.

To be clear, it's not that it's impossible to create such a calculation, it's that you've not provided the relationships, and one is not readily apparent. There may be a function, the sequence of which would result in the elements of your sum or product. But it's not given, and it's not obvious.

From this source, where the symbol "∑" is said to represent an iteration, you could call expressions such as "1 + 5 + 3 + 2 + 4 + 100" iterated sums (similarly for products).

You can also speak of repeated sums (Notation) (similarly for products).
