The commutative property of multiplication tells us that it doesn't matter if the 1 comes before or after the number. Here's an example of the identity property of multiplication with the 1 before the number:

The distributive property is a combination of multiplication AND addition, though! It's how multiplying after adding the 2 numbers is the same as multiplying them separately before adding.

Practice changing the order of factors in a multiplication problem and see how it affects the product.

What is the distributive property? The distributive property says that in a multiplication problem, when one factor is rewritten as the sum of two numbers, the product doesn't change.

There are inverse and identity properties for multiplication and addition, but there aren't any for subtraction, and division as well. I hope that sufficiently answers your question :)

Review the basics of the commutative property of multiplication, and try some practice problems.

The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because …

The multiplicative identity property states that the product of any n × n matrix A and I n is always A , regardless of the order in which the multiplication was performed.

My question stems from the issue of simplifying and resolving complex algebraic equations where an intermediate step may result in dividing by 0 but that portion cancels.

The associative property of matrices applies regardless of the dimensions of the matrix. In the case A·(B·C), first you multiply B·C, and end up with a 2⨉1 matrix, and then you multiply A by this matrix.
