# Commutative property of multiplication review

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

### What is the commutative property?

The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
Example:
$8×2=16$
$\phantom{\rule{1em}{0ex}}$
$2×8=16$
So, $8×2=2×8$.

## Practice

Problem 1
Complete the equation.
$×\phantom{\rule{0.167em}{0ex}}4$
$\phantom{\rule{2em}{0ex}}$

• if there are 4 rows of 3 and 3 rows of 4 is it still the same
• They still have the same number but instead of having larger columns you have larger rows.
• can you give more exercises?

• define commutative property
• The word "commutative" comes from "commute" or "move around"
You can move around multiplication like this:
2x4=8
4x2=8
This is the commutative property of multiplication.
• This is extremely easy!
• what is the commutative property in a bigger scale. like what is this: -1.2×3×100 = -1.2×100×3
= -120 × 3

= -360
