The operands for multiplication are called 'factors'.
When you round both factors in a multiplication problem up, your estimate will be greater than the actual product.
when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.
One fact about a factor is that there are at least 2 in a multiplication problem.
There is only one associative property for multiplication: there is not a separate "regular" version.
As a product of its prime factors: 3*19 = 57
As a product of its prime factors it is: 3*11 = 33
As a product of its prime factors: 2*71 = 142
AS a product of its prime factors: 7*13 = 91
A product is an answer to a multiplication problem.
