Multiplication of Integers Exercises – Set 1

Below are exercises on multiplication of signed numbers. Part I and II are exercises for multiplication of integers, while part III is an extension to fractions and decimals. I have written the exercises using the \times notation as well as the parenthesis to familiarize you with both notations.

Solutions and answers can be found here.

Part I

1. 2 \times (-3)

2. -4 \times -7

3. -9 \times 3

4. 7 \times 7

5. -11 \times 3

6. (12)(-4)

7. (-6)(-3)

8. (9)(0)

9. (-5)(3)

10. (13)(3)

Part II

1. 2 \times 3 \times (-4)

2. -4 \times 8 \times 1

3. -4 \times (-3) \times 3

4. -6 \times 2 \times (-5)

5. -12 \times 13 \times 0

6. (-6)(-1)(2)

7. (-5)(8)(3)

8. (-7)(-1)(-3)

9. (11)(8)(-1)

10. (-2)(-1)(7)(3)

Part III

1. \frac {1}{2} \times (-\frac {1}{3})

2. -\frac {1}{5} \times (-\frac {5}{8})

3. -\frac {3}{4} \times \frac {1}{6}

4. \frac {2}{7} \times \frac {1}{4}

5. -\frac {6}{11} \times \frac {2}{3}

6. 0.5 \times (-3)

7. -0.2 \times (0.4)

8. -3 \times (-0.1)
