If both factors are positive, keep the numbers as they are. On the other hand, if the factors are both negative, ignore the signs of the factors to reduce the multiplication to a multiplication of two positive integers. In this example, the signs of the integers will be removed because both are negative. -3*(-4) ⇕ 3*4 The expression is now a multiplication of two whole numbers.
Verify that one factor is positive and the other is negative. Change the negative factor to its opposite. The result is a multiplication of two positive integers. For the given example, the first factor is negative 7, so change it to its opposite 7. -7*2 ⇒ 7*2
Change the product from the previous step to its opposite to get the product of the initial multiplication of integers with different signs. For the given example, the product of whole numbers is 14. Its opposite is -14. 7*2= 14 ⇒ -7*2= -14 In summary, multiply two integers with different signs as if they were whole numbers and change the result to its opposite to get the final product.
If the dividend and the divisor are positive, keep the numbers as they are. On the other hand, if the dividend and the divisor are negative, ignore their sings to reduce the division to a division of two positive integers. In the given example, the signs of the integers will be removed because both are negative. -15÷(-3) ⇔ 15÷ 3 The expression is now a division of two whole numbers.
Identify which of the numbers involved in the division is negative. Next, change it to its opposite to get a division of two positive integers. In the given example, the dividend -12 is negative. Its opposite is 12. -12÷4 ⇒ 12÷4
Change the quotient found in the previous step to its opposite to get the quotient of the initial division of integers with different sings. For the given example, the quotient is 3. Its opposite is -3. Therefore, the quotient of - 12 ÷ 4 is - 3. 12÷4= 3 ⇒ -12÷4= -3 In summary, divide two integers with different signs as if they were whole numbers and change the result to its opposite to get the final quotient.
