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

Think-Pair-Share What two numbers will give you a product of 64 and a quotient of 4?

2
Solution 16 and 4 16 x 4 = 64 16 ÷ 4 = 4

3
Adding Integers

4
Adding Integers We can use positive and negative counters to model the addition of integers. Positive Integer Negative 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
**Adding Integers with like signs. **

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
= -2 Add Remove all the zero pairs.

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

12
= -1 Add Remove all the zero pairs.

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

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
**Let’s try a few examples using the rules for adding integers.**

-20 -6 12 -2 -38 13 1) = 2) = 3) (-19) = 4) = 5) = 6) (-16) = 7) (-5) =

16
**Summary 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.
