Multiplication in the purest form is just chunked repeated addition. You are just adding on a grand scale. The same could be said about division, but with respect to the operation of subtraction. Division can also be seen as sharing, the denominator is just an indication of how many groups or sets you are sharing the numerator across. This series will offer you some review with calculating products and quotients.
Tips for Multiplying and Dividing Integers - We divide or multiply integers with whole numbers as you must keep the sign on the right track. Multiply or divide the given values by absolute values with integer's signs. Always use these rules to define answer's signs. Multiplication of Integers - You will always get the positive answer when you multiply two integers with the same sign. Then, you will multiply the absolute values to make positive answer. +ve × -ve = positive, -ve × -ve = positive. Your multiplication result will always be negative when you use different signs in the multiplication of two integers. For negative answer, you will need to multiply absolute values. +ve × -ve = -ve, -ve × +ve = -ve. Division of Integers - We always get the positive answer when we use the same signs in the division of two integers. Therefore, you need to divide the absolute values for the positive result. +ve/+ve = +ve, -ve/-ve = +ve. You will always get the negative answer if you are dividing two integers with different signs. Therefore, make the result negative by dividing the absolute value. +ve/-ve = -ve, -ve/+ve = -ve. Examples: -5 × - 4 = + {(-5 × -4) = + ( 5 × 4) = + 20 = 20 -10/-5 = -10/-5 = - (3 × 8 ) = -24 These worksheets explain multiplying and dividing positive and negative integers. In some cases, students will be asked to identify the correct sign for the answer.
