WHY IS A NEGATIVE DIVIDED BY A NEGATIVE A POSITIVE?
-1-1 = 1
IN ORDER TO ANSWER THIS LET’S LOOK AT DIVIDING NUMBERS AND LOOK FOR A
PATTERN.
20 / 218 / 216 / 214 / 212 / 210 / 2
8 / 26 / 24 / 22 / 20 / 2
= 10= 9= 8= 7= 6
= 5= 4= 3= 2= 1= 0
What two pattern do you see developing in this list of numbers?
What are the next three dividends?
What happens to the totals as we decrease
the dividend?

-2 / 2-4 / 2-6 / 2
= -1= -2= -3
That’s right! Our dividends would
be -2, -4 and -6
Outstanding! Our quotients would
be -1, -2 and -3
What would be the next three quotients?
6 / 24 / 22 / 20 / 2
= 3= 2= 1= 0
What are the next three dividends?
WHY IS A NEGATIVE TIMES A NEGATIVE A POSITIVE?
-1* -1= 1
IN ORDER TO ANSWER THIS LET’S LOOK AT MULTIPLYING NUMBERS AND LOOK
FOR A PATTERN.
What pattern do you see developing in the
multiplier?
20 * 218 * 216 * 214 * 212 * 210 * 2
8 * 26 * 24 * 22 * 20 * 2
= 40= 36= 32= 28= 24
= 20= 16= 12= 8= 4= 0
What are the next three Multipliers?
What happens to the totals as we decrease
the Multiplier?

= - 4= - 8= - 12
-2 * 2-4 * 2-6 * 2
= - 4= - 8= - 12
That’s right! Our multipliers would
be -2, -4 and -6
Outstanding! Our products would be
-4, -8 and -12
What would be the next three products?
What are the next three multipliers?
6 * 24 * 22 * 20 * 2
