Question Video: Applying the Commutative Property of Addition Mathematics • 3rd Grade

Video Transcript

Find the missing number: 880 plus 6207 equals what plus 880.

Let’s imagine it like this. Here is a block of 880. And here is a block of 6207. Inside this bottom block, it’s equal to 880 plus 6207. Inside that third space, you fill it with 880. What is remaining? The remaining space is 6207.

You see the Commutative property of addition tells us that changing the order of the operands, the operands being the values that you’re adding together, does not change the result. If you change the order in which you add two numbers, you don’t change the result. Here 880 plus 6207 is equal to 6207 plus 880.
