It is good to compare when you shop for something that costs a lot of money.
Example: Houses:
| House 1 | House 2 | |
|---|---|---|
| Cost | $100,000 | $90,000 |
| Bedrooms | 4 | 3 |
| Bathrooms | 2 | 1 |
| Garage | no | yes |
| Yard size | ½ acre | 1 acre |
House 1 costs more than House 2.
House 1 has one more bedroom than House 2.
House 1 has 2 bathrooms, but House 2 has only one bathroom.
House 1 does not have a garage, but House 2 does.
House 1 has a smaller yard than House 2.
You can make a chart to help you compare the two houses.
| House 1 | House 2 | |
|---|---|---|
| This house is cheaper. | |
|
| This house has more bedrooms. | |
|
| This house has more bathrooms. | |
|
| This house has a garage. | |
|
| This house has a bigger yard. | |
