Answer :

Let's tackle these problems step-by-step. The task is to multiply pairs of integers, including both positive and negative numbers. When multiplying:

  1. A positive number and a negative number, the result is negative.
  2. Two negative numbers, the result is positive.
  3. Two positive numbers, the result is positive.

Let's solve each multiplication problem one by one:

  1. [tex]7 \times -2 = -14[/tex]
    Multiply the positive 7 by negative 2 to get -14.

  2. [tex]5 \times -4 = -20[/tex]
    Multiply the positive 5 by negative 4 to get -20.

  3. [tex]-7 \times 7 = -49[/tex]
    Multiply the negative 7 by positive 7 to get -49.

  4. [tex]5 \times 7 = 35[/tex]
    Multiply the positive 5 by positive 7 to get 35.

  5. [tex]10 \times -5 = -50[/tex]
    Multiply the positive 10 by negative 5 to get -50.

  6. [tex]-6 \times 8 = -48[/tex]
    Multiply the negative 6 by positive 8 to get -48.

  7. [tex]-10 \times 2 = -20[/tex]
    Multiply the negative 10 by positive 2 to get -20.

  8. [tex]-7 \times 5 = -35[/tex]
    Multiply the negative 7 by positive 5 to get -35.

  9. [tex]-3 \times 6 = -18[/tex]
    Multiply the negative 3 by positive 6 to get -18.

  10. [tex]9 \times 7 = 63[/tex]
    Multiply the positive 9 by positive 7 to get 63.

  11. [tex]4 \times -9 = -36[/tex]
    Multiply the positive 4 by negative 9 to get -36.

  12. [tex]-4 \times 10 = -40[/tex]
    Multiply the negative 4 by positive 10 to get -40.

  13. [tex]5 \times -3 = -15[/tex]
    Multiply the positive 5 by negative 3 to get -15.

  14. [tex]-4 \times -9 = 36[/tex]
    Multiply the negative 4 by negative 9 to get a positive result, 36.

  15. [tex]1 \times 3 = 3[/tex]
    Multiply the positive 1 by positive 3 to get 3.

These common multiplication rules apply for integers and help in solving arithmetic problems efficiently.
