The commutative property of multiplication states that multiplying two numbers will get the same result no matter which number comes first.^{[1]} The order in which two numbers are multiplied does not change the product. This is expressed by the equation: a·b = b·a.

One way to remember the commutative property of multiplication is to use the root word, 'commute'. Commute means to travel from one place to another, such as commuting to work. As diagrammed in figure 1, in the commutative property of multiplication, the variable 'a' commutes to where the 'b' was, and the variable 'b' commutes to where the 'a' was. 

Figure 2 is a representation of the commutative property of multiplication using dots. On the left is a rectangle showing 2·3. On the right is a rectangle showing 3·2. Both have six dots in them. You can transform the first into the second by turning the first on its side. 

Figure 3 is a representation of the commutative property of multiplication that uses the length of a line segment to represent each number, and right angles to represent multiplication. Notice that when we 'multiply' one by the other, it doesn't matter which comes first, the total area is the same. Click on the yellow points of the two lines on top and drag the points. Dragging these points changes the diagram showing that, for any values of 'a' and 'b', this property holds true.
