Multiplication and Division 4

Multiplication and division with the calculator are practiced in a playful manner, so that it can later be used as a control tool when needed. Following this, the topics of "Calculating with Parentheses" as well as inequalities and equations are addressed, followed by multiplication and division with large, round numbers in the extended number range. In the second section of the topic booklet, the method of written multiplication is introduced and practiced. Multiples, divisors, prime numbers, and divisibility are the subjects of the following section, which prepares for the subsequent written division. Pages for calculations in real-life situations and for "Puzzling with the Calculator" complement the range of topics.
