    • 1. Integers!By: Atom 20 and Atom 7
    • 2. Introduction
    • 3. Introduction• Integers use both positive and negative numbers• Positive numbers are numbers that are above zero. (e.g. 7 or 20)• Negative numbers are numbers that are below zero. (e.g. -6 or -28)
    • 4. The Number Line• The number line is a very useful tool to help you figure out the answers of integer problems. Think of it as a tool.
    • 5. Rules
    • 6. Rules• When you add, subtract, multiply or divide negatives you have to remember these rules or else you’ll answer the question incorrectly!
    • 7. Operation Rules• Use the number line to help your understanding for these problems:• Addition: -2 + 1= ? 5 + -3= ? Tricky one coming up: -6 + -2 = ?• Subtraction: 1-6=? -1-2=? tricky one: 1--1=?
    • 8. Wacky Facts And Opinions
    • 9. Wacky Facts And Opinions• Fact: A negative number plus it’s positive is zero: 1+-1= 0 or -1+1= 0.• Opinion (Atom 7): Multiplication and division with integers is easier than addition and subtraction with integers.• Fact: Every positive integer has a corresponding negative integer. (e.g. -3 and 3).• Opinion (Atom 20): Multiplying integers are really easy. Subtracting integers are the hardest.• Fact: Subtracting a negative integer is the same as adding a positive integer.• Fact: Zero is not an integer.
    • 10. Conclusion
    • 11. Conclusion• Integers can be very confusing but if you understand the concepts you’ll be a master!
