1. 1. Integers
2. 2. Integers By: Sophia L
3. 3. What Are They?
4. 4. What Are They?• They are numbers that are below 0 (-4)• Or just a normal positive number (4)• They are whole numbers not fractions
5. 5. Negative Integers
6. 6. Negative Integers• The ones closer to zero are bigger• They all have a - sign next to
7. 7. Negative Integers• The ones closer to zero are bigger• They all have a - sign next to
8. 8. Negative Integers • The ones closer to zero are bigger • They all have a - sign next to This is thenegative side
9. 9. Negative Integers • The ones closer to zero are bigger • They all have a - sign next to This is the This is thenegative side positive side
10. 10. Positive Integers
11. 11. Positive Integers• A positive integer are the numbers we worked with since we were young• For example 4 can also be written
12. 12. Positive Integers• A positive integer are the numbers we worked with since we were young• For example 4 can also be written
13. 13. Number Lines
14. 14. Number Lines
15. 15. Number Lines Number lines are a great way to do integerproblems because you can take a look at how the adding/ subtraction, multiplying or dividing works.
16. 16. Adding Integers
17. 17. Adding Integers For Example: -4 + -5
18. 18. Adding Integers For Example: -4 + -5When both of the numbers have thesame signs then you can treat it likenormal adding then adding the sign they have (-, +)
19. 19. Adding Integers For Example: -4 + -5 Answer: 9When both of the numbers have thesame signs then you can treat it likenormal adding then adding the sign they have (-, +)
20. 20. Adding Integers
21. 21. Adding Integers For Example: -4 + (- 6)
22. 22. Adding Integers For Example: -4 + (- 6) When there is a bracket thenumber in the bracket becomes the opposite. So this problem becomes -4 + 6.
23. 23. Adding Integers For Example: -4 + (- 6) Answer: -10 When there is a bracket thenumber in the bracket becomes the opposite. So this problem becomes -4 + 6.
24. 24. Subtracting Integers
25. 25. Subtracting Integers For Example: -10 - 9
26. 26. Subtracting Integers For Example: -10 - 9 You can treat it as 10 +9 because itbecomes positive and it becomes the opposite
27. 27. Subtracting Integers For Example: -10 - 9 Answer: 19 You can treat it as 10 +9 because itbecomes positive and it becomes the opposite
28. 28. Multiplying Rules: Positive x Positive = PositiveNegative x Negative = PositiveNegative x Positive = NegativePositive x Negative = Negative
29. 29. Multiplying Integers Multiplying Rules: Positive x Positive = Positive Negative x Negative = Positive Negative x Positive = Negative Positive x Negative = Negative
30. 30. For Example: -4 x -5 = Answer: 20 You can treat this like a normal multiplicationproblem, because a negative integer multiplied by another negative integer is a positive number.
31. 31. Multiplying Integers For Example: -4 x -5 = Answer: 20 You can treat this like a normal multiplicationproblem, because a negative integer multiplied by another negative integer is a positive number.
32. 32. Dividing Integer
33. 33. Dividing Integer• Basically it’s the same as multiplying but in reverse but all of the rules reply just the same
