Logical examples are additionally included for training of calculation by a comfortable method.How to understand, is skill of account led to automatism? On every sign of action 3-4 is taken p.

For the best mastering of material it is recommended to decide for ten examples in a day. A manual can be used on the lessons of mathematics and for independent work of house.
