A math problem in grade three, please have a look and express your views.

There should be a condition that you have to pay a property fee when you buy a house.

First, the house discount is 8 100, but don't forget that you have to pay the property fee, which is not a discount.

So the overall discount is 8 100-3600=4500.

Second, the house is not favorable, but the property fee is 3600.

So the overall discount is 3600.

Remarks, that must be posted, so be sure to ask clearly when buying a house. Sometimes the seller will play word games with you, so you must read the contract clearly.
