If x represents objects.

For 5:

For 6:

We can see that 11 objects result.

1. Add the ones places:

2. Add the tens places:

***don't forget to put the 3 down and carry the one to the hundreds place***

3. Add the hundreds place:

This makes your total:

First add the digits in the ones colume, this would be . Make sure to carry the 1 from the 17 to the tens colume.

Then add the digits in the tens colume, this would be .

Lastly, add the digits in the hundrends colume, this would be

Therefore the result is as follows:

We can see this because if we had 5 (represented by ) and add another 2 objects (represented by ) we should get 7 objects ( and ) total.

We have 7 objects total!
