3000 examples in mathematics. Best training. We multiply. Divide. Examples with "windows". With methodological recommendations. 3

The Multiplication Table is one of the basic topics of the elementary school mathematics. After step -by -step development of multiplication and division by 2, by 3, etc (in a similar book for grade 2) We offer examples for tabular multiplication and division mixed, which will allow you to work out the score to automatism.
In the examples with the windows one of the components of multiplication (the first multiplier, the second multiplier, work) or a sign of action was missed.
