5. What Are They?

6. What Are They?
• They are numbers that are below 0
(-4)
• Or just a normal positive number (4)
• They are whole numbers not
fractions

8. Negative Integers

9. Negative Integers
• The ones closer to zero are
bigger
• They all have a - sign next to

10. Negative Integers
• The ones closer to zero are
bigger
• They all have a - sign next to

11. Negative Integers
• The ones closer to zero are
bigger
• They all have a - sign next to
This is the
negative side

12. Negative Integers
• The ones closer to zero are
bigger
• They all have a - sign next to
This is the This is the
negative side positive side

14. Positive Integers

15. Positive Integers
• A positive integer are the numbers
we worked with since we were
young
• For example 4 can also be written

16. Positive Integers

18. Number Lines

19. Number Lines

20. Number Lines
Number lines are a great way to do integer
problems because you can take a look at how the
adding/ subtraction, multiplying or dividing
works.

22. Adding Integers

23. Adding Integers
For Example:
-4 + -5

24. Adding Integers
For Example:
-4 + -5
When both of the numbers have the
same signs then you can treat it like
normal adding then adding the sign
they have (-, +)

25. Adding Integers
For Example:
-4 + -5
Answer: 9
When both of the numbers have the
same signs then you can treat it like
normal adding then adding the sign
they have (-, +)

27. Adding Integers

28. Adding Integers
For Example:
-4 + (- 6)

29. Adding Integers
For Example:
-4 + (- 6)
When there is a bracket the
number in the bracket becomes
the opposite. So this problem
becomes -4 + 6.

30. Adding Integers
For Example:
-4 + (- 6)
Answer: -10
When there is a bracket the
number in the bracket becomes
the opposite. So this problem
becomes -4 + 6.

32. Subtracting
Integers

33. Subtracting
Integers
For Example:
-10 - 9

34. Subtracting
Integers
For Example:
-10 - 9
You can treat it as 10 +9 because it
becomes positive and it becomes the
opposite

35. Subtracting
Integers
For Example:
-10 - 9
Answer: 19
You can treat it as 10 +9 because it
becomes positive and it becomes the
opposite

36. Multiplying Rules:
Positive x Positive = Positive
Negative x Negative = Positive
Negative x Positive = Negative
Positive x Negative = Negative

37. Multiplying Integers
Multiplying Rules:
Positive x Positive = Positive
Negative x Negative = Positive
Negative x Positive = Negative
Positive x Negative = Negative

38. For Example:
-4 x -5 =
Answer: 20
You can treat this like a normal multiplication
problem, because a negative integer multiplied
by another negative integer is a positive
number.

39. Multiplying Integers
For Example:
-4 x -5 =
Answer: 20
You can treat this like a normal multiplication
problem, because a negative integer multiplied
by another negative integer is a positive
number.

41. Dividing Integer

42. Dividing Integer
• Basically it’s the same as multiplying but in
reverse but all of the rules reply just the
same
