can you help me with math I don't understand that.

Question

Rewrite the expression using the given property of real numbers.
Commutative Property of Addition,
x + 3

Answer 1

Don't worry about solving x. We are just writing a different expression that is equal to the one they gave us: x+3

If you look at your notes or the text provided by your class, the Commutative Property simply tells us that we can switch the order of things that are adding together.

• Think of your parents driving to work.
• They might have to get on the highway, go through traffic in the blistering sun, back and forth every weekday.
• That's what people call the Daily Commute

So when you think about Commutative Property, think Commute. All the numbers get to move and zip around as long as they have the "road" of addition to connect them.

 

You've probably seen it before...

1+2+3 = 6

2+1+3 = 6

3+2+1 = 6

1+3+2 = 6

All those expressions add up to give you the same value of 6, the order doesn't matter. And that's something that we want to give a name, so we call it the Commutative Property.

 

To answer your question, another expression that is equal to the one that they gave us is 3+x 

There are only four Properties for Addition, and they make math easy and fun. I highly suggest you memorize them like the back of your hand! Have a great weekend :)

Answer 2

3+X

 

The order of addition does not matter

Answer 3

Commutative Property of Addition:  a + b = b + a

 

3 + 7 = 7 + 3

 

x + y = y + x

 

5 + x = x + 5

 

x + 3 = ______
