What steps should I take to achieve the desired outcome?
Given a matrix $A = left[beginarrayccc 2 & 3 & 5\ 1 & 4 & 11endarrayright]$, the steps should result in a scalar $x$ equal to the summation of the products of each row, i.e., for this $A$, $x = (2*3*5) + (1*4*11) = 74$.
I think it is called the cumulative product operation in MATLAB.
There must be some established notation as it such a simple concept.

"There must be some established notation as it such a simple concept." That is nonsense. There are a lot of simple concepts that don't have any established notation. Just because something is simple doesn't mean it needs or has a special notation. Why do you ask? What prevents you from just setting up a notation yourself?

I try to confirm that there is not something already established, before settling on my own notation. Do you not do the same?
