1
What two numbers will give you a product of 64 and a quotient of 4?

2
16 and 4 16 x 4 = ÷ 4 = 4

4
Adding Integers We can use positive and negative counters to model the addition of integers. Positive IntegerNegative Integer A positive integer paired with a negative integer form a zero pair. The value of a zero pair is 0.

5
Add -2 + (-4)= -6

6
Add 5 + 6= 11

7
Add -3 + (-5) = -8

8
Add = -5

9
Do you notice a pattern or rule? Comp book page 24 Adding Integers with like signs. - add their absolute values, keep the same sign as the integers. Examples: -7 + (-3) = = 9

10
Add Remove all the zero pairs. = -2

11
Add 4 + (-1) = 3 Remove all the zero pairs.

12
Add Remove all the zero pairs. = -1

13
Add 3 + (-7) Remove all the zero pairs. = -4

14
Did you notice a pattern or rule? Comp book page 24 Adding integers with unlike signs. - When the signs are different, subtract their absolute values, keep the same sign as the integer with the greater absolute value. Examples: 8 + (-3) = = -5

15
Lets try a few examples using the rules for adding integers. 1) = 2) = 3) 13 + (-19) = 4) = 5) = 6) (-16) = 7) 18 + (-5) =

16
Adding Integers with like signs. - add their absolute values, keep the same sign as the integers. Adding integers with unlike signs. - When the signs are different, subtract their absolute values, keep the same sign as the integer with the greater absolute value.
