Multiplying integers word problems: This lesson will show you how to solve five word problems related to the multiplication of integers. Interesting multiplying integers word problemsProblem #1 From sea level, a submarine descends 40 feet per minute. Where is the submarine in relation to sea level 5 minutes after it starts descending? Solution In 1 minute, the submarine is 40 feet below sea level. This situation can be represented with -40 feet. Notice that we use a negative sign since the submarine is descending. After 5 minutes, the submarine is at -40 × 5 = -200 feet Problem #2 The price of one share of a stock fell 4 dollars each day for 8 days. How much value did one share of the stock lose after 8 days? Solution Each day, one share of the stock goes down by 4 dollars. We can represent this situation with the integer -4 dollars. After 8 days, one share of a stock has gone down by -4 × 8 = -32 One share of a stock is now worth 32 dollars less. Problem #3 A test has 20 questions. The test awards 3 points if the answer is correct and takes away 1 point if the answer is incorrect. A student answered 5 questions incorrectly. How many points did the student lose? Solution For each incorrect answer, the student gets -1 point. After answering 5 questions incorrectly the student get -1 × 5 = -5.

At the customer's request and out of courtesy, the credit card company decides to cancel all late fees for that year. Write a numerical expression to show how much money was return. Solution The amount of late fee the bank charged last year was -25 × 4 In order to return the money, the bank can do this math: -25 × -4 Notice how the number 4 became negative.
