NumberHouses - learning math description

Number houses are arithmetic problems that are represented in the form of a house. That is why they are also called number houses. The house consists of a roof and several floors. In the roof is a number that is called the roof number. Below are the floors, each consisting of two rooms. Imagine that in a house only the numbers are allowed to live on one floor, which together make up the number on the roof. When solving, each floor is therefore considered separately.
