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? Adding Integers with like signs. - When the signs are the same, add the numbers together and keep the sign.

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? Adding integers with unlike signs. - When the signs are different, subtract the integers and keep the sign of the larger digit.

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. - When the signs are the same, add the numbers together and keep the sign = -12 Adding integers with unlike signs. - When the signs are different, subtract the integers and keep the sign of the larger integer = -6

17 Homework: Lesson 3-4 #2-22 evens
