`<cumulativeProduct>`

Running product of the child math or number values: the list of partial products

<cumulativeProduct> is a Math Operator component that renders the running product of its arguments: a list whose $n$ th entry is the product of the first $n$ input values.

It is to <product> what <cumulativeSum> is to <sum>.
