How to solve examples? Children parents often ask such question if lessons it is required to make houses. How it is correct to explain to the child the solution of examples on addition and subtraction of multidigit numbers? Let's try to understand it.

Instruction
1. Read an example. For this purpose each multidigit number needs to be broken into classes. Since the end of number, we count three figures and we put an end (23.867.567). Let's remind that the first three figures since the end of number belong to the class of units, following three - to a class of thousands, go further millions. We read number: twenty three million eight hundred sixty seven thousand five hundred sixty seven.
2. Write down an example in a column. Pay attention that units of each category register strictly the friend under the friend: units under units, dozens under dozens, hundreds under hundreds, etc.
3. Execute addition or subtraction. Begin to perform operation from units. Write down result under that category with which operation was performed. If the two-digit number (turned out at addition), then we write down units on the place of the answer, and we add number of dozens to units of the following category. If the number of units of any category in reduced less, than in subtracted, we occupy 10 units of the following category, we perform operation.
4. Read the answer.
