Find the value of (-6)(4). Explain how you decided the sign.
When the signs are different, the answer is negative.
The value is -24. A negative number times a positive number gives a negative product. - 2
Find the value of (-8)(-3). Explain how you decided the sign.
The value is 24. A negative number times a negative number gives a positive product. - 3
Find the value of 45 ÷ (-9). Explain how you decided the sign.
Different signs make a negative answer.
The value is -5. A positive number divided by a negative number gives a negative quotient. - 4
Find the value of (-56) ÷ (-7). Explain how you decided the sign.
The value is 8. A negative number divided by a negative number gives a positive quotient. - 5
Complete the sign chart for multiplication: positive times positive, positive times negative, negative times positive, and negative times negative.
Same signs give a positive product, and different signs give a negative product.
Positive times positive is positive. Positive times negative is negative. Negative times positive is negative. Negative times negative is positive. - 6
Without multiplying first, decide whether (-12)(5)(-2) is positive or negative. Then find the value.
An even number of negative factors gives a positive product.
The expression is positive, and the value is 120. There are two negative factors, so the product is positive. - 7
Without multiplying first, decide whether (-4)(-3)(-2) is positive or negative. Then find the value.
The expression is negative, and the value is -24. There are three negative factors, so the product is negative. - 8
A submarine descends at a rate of 6 meters per minute. Write the rate as -6 meters per minute. How far has the submarine moved after 5 minutes? Use integer multiplication.
A descent can be represented by a negative number.
The submarine has moved -30 meters. The expression is (-6)(5) = -30, which means it descended 30 meters. - 9
A quiz has a penalty of -2 points for each incorrect answer. If a student gets 7 answers incorrect, what is the total penalty?
The total penalty is -14 points. The expression is (-2)(7) = -14. - 10
A temperature changes by -24 degrees over 6 equal hours. What is the temperature change per hour? Use integer division.
A total decrease divided into equal time periods stays negative.
The temperature change per hour is -4 degrees. The expression is (-24) ÷ 6 = -4. - 11
Fill in the missing sign to make the equation true: (-9) ÷ (3) = 3 or -3. Explain your choice.
The correct answer is -3. A negative number divided by a positive number gives a negative quotient. - 12
Choose the expression with a positive result: A. (-5)(6), B. 18 ÷ (-3), C. (-4)(-7), or D. (-20) ÷ 5. Explain your choice.
Look for same signs when multiplying or dividing.
Expression C has a positive result. The expression (-4)(-7) has two negative numbers, so the product is positive.
