excel function within a function

[David]

a1 2
a2 3
a3 =+A1*A2/A1
Maybe this is too simple or I don't understand the
question?

I need to divide the product of a set of cells by the

data in one of the cells used to find product. For
example, the product of A1 and A2 divided by A1. Can
anyone help? Thanks.
