Arithmetic operations within 1000

The mathematical simulator is designed for students to work out elementary grades (3-4 grades) of arithmetic skills with two-digit and three-digit numbers. Tasks for oral and written accounts are provided, to assimilate the features of addition, subtraction, multiplication and division of multi -digit numbers, and tasks requiring the use of several account skills at once. A notebook is recommended both for work in the classroom and for individual independent training of students at home under adult control. At the end of the notebook, brief answers to all tasks are given. The simulator can be used as an additional manual for the mathematics textbook of any educational and methodological kit
