Multiplication And Division Rules Rule: Multiplication and Division are more important than Addition and Subtraction. This means that we need to carry out Multiplication and Division first before we can carry out Addition and Subtraction. Rule: Parentheses or Brackets () are more important than each of the 4 operations. Multiplication and division, are inverse operations of each other. If we say, a multiplied by b is equal to c, then c divided by b results in a. Mathematically, it can be represented as: a × b = c; c ÷ b = a; For example, 4 x 5 = 20 [4 multiplied by 5 results in 20] 20 ÷ 5 = 4 [20 divided by 5 returns back 4] Multiplication and Division Rules Multiplication is finding the product of two or more numbers, and division is finding the quotient of two numbers. Multiplication is basically the repeated addition of equal groups. For example, 4 4 equal groups of 3 3: In a multiplication equation, the answer to multiplying one number by another is called the product. The rules of multiplication and division are as follows: Multiplication. To multiply the numbers, we follow the given rules: Rule 1: The product of two numbers of opposite signs is equal to the additive inverse of the product of their absolute values. Example: 7 × ( - 4) = - ( 7 × 4) = - 28. ( - 8) × 5 = - ( 8 × 5) = - 40. Division of Integers. Consider that \(\frac{12}{3} = 4\) because \(3(4) = 12\) and \(\frac{-12}{-3} = 4\) because \(-3(4) = -12\). In like manner, \(\frac{12}{-3} = -4\) because -3(-4) = 12 and \(\frac{-12}{3} = -4\) because \(3(-4) = -12\). Thus, the rules for dividing integers are the same as the rules for multiplying integers. 8. Double, double, double! Example: 8×6: double 6 is 12, double 12 is 24, double 24 is 48. 9. is 10× the number minus the number. Example: 9×6 = 10× 6 − 6 = 60−6 = 54. the ones digit goes 9, 8, 7, 6, ...: 9, 1 8, 2 7, 3 6, 4 5, ... the tens digit goes 0, 1, 2, 3, ...: 9, 1 8, 2 7, 3 6, 4 5, ...
