Last week we added and subtracted integers. Take a second to review the rules above.

This week we will multiply and divide integers.

Watch this video to understand how we multiply and divide. (I would take a couple of notes if I were you. :)

**Note: He uses the word "minus" interchangeably for "negative." Don't let that confuse you.
So, in summary, there are really two steps:
  1. Multiply and divide focusing only on the numbers, ignoring the signs.
  2. If both signs in the problem are the same the answer is positive. If the signs are different the answer is negative.

Drag the problem to the correct solution. Will its answer be positive or negative?

  • -4 x 7 =
  • -1 x 12 =
  • -6 x -3 =
  • -20 / -5 =
  • -18 / 3 =
  • 36 / 12 =
  • Positive Result
  • Negative Result
