Find the product, using suitable properties: The given equation is in the form of Distributive law of Multiplication over Addition. a × 1 = 1 × a = a, Multiplication with (-1): Let us observe the following table showing the product of an integer and (-1). We can say that if dividend and divisor are of same signs, then the quotient is a positive integer. Temperature at the beginning i.e., at 12 noon = 10oC, Rate of change of temperature = – 2oC per hour, Temperature at 1 PM = 10 + (-2) = 10 – 2 = 8oC, Temperature at 2 PM = 8 + (-2) = 8 – 2 = 6oC, Temperature at 3 PM = 6 + (-2) = 6 – 2 = 4oC, Temperature at 4 PM = 4 + (-2) = 4 – 2 = 2oC, Temperature at 5 PM = 2 + (-2) = 2 – 2 = 0oC, Temperature at 6 PM = 0 + (-2) = 0 – 2 = -2oC, Temperature at 7 PM = -2 + (-2) = -2 -2 = -4oC, Temperature at 8 PM = -4 + (-2) = -4 – 2 = -6oC, Temperature at 9 PM = -6 + (-2) = -6 – 2 = -8oC, ∴At 9 PM the temperature will be 8oC below zero, The temperature at mid-night i.e., at 12 AM, Change in temperature in 12 hours = -2oC × 12 = – 24oC, So, at midnight temperature will be = 10 + (-24).
