The document discusses subtracting integers using the additive inverse. It provides examples such as 4 - (-6) = 4 + 6 = 10 by adding the additive inverse. Students are asked to practice subtracting integers by adding the additive inverse. The document also discusses multiplying and dividing integers by explaining the rules for determining the sign of the product or quotient based on the signs of the factors or dividend and divisor.

1. Learning Objective: SWBAT subtract integers using the additive inverse.

2. Use the flow chart to subtract 4 – (-6)

3. Learning Objective: SWBAT subtract integers using the additive inverse. Key Concept: Subtracting Integers. TO SUBTRACT INTEGERS, ADD ITS OPPOSITE OR ADDITIVE INVERSE a.k.a Keep Change Change Example: 4 – 7 = 4 + (-7) “ To subtract 7, add -7” 9 – 12 = -6 – 8 = 7 – (-15) = 7 + (+15) “ To subtract -15, add 15” -30 – (-20) =

4. Learning Objective: SWBAT subtract integers using the additive inverse. Your Turn: Show that your adding the additive inverse 3 – 7 = -6 – (-9) = 11 – (-8) = -6 – 2 = 15 – (-3) = -7 – (-11) =

5. Learning Objective: SWBAT subtract integers using the additive inverse. Evaluate Algebraic Expressions: Use the rules for subtracting integers to evaluate Evaluate each expression if a = 9, b = -8, and c= -2. 14 – b 14 - b = 14 - (-8) (common error is to replace b with 8 instead of -8 to prevent this error use parentheses before replacing the variable with its value.) c – a -3 – b c – (-8) a – b - 3

6. Learning Objective: SWBAT subtract integers using the additive inverse. Guided practice: Page 30 #’s 30 – 41 Journal Prompt: Page 30 # 2

7. Learning Objective: SWBAT multiply and divide integers. Review Vocabulary: FACTOR: Numbers that are multiplied together. PRODUCT: the result when two or more numbers are multiplied together. DIVIDEND : is the number you are dividing. (Ex 12 ÷3=4) 12 is the dividend DIVISOR: is the number you are dividing by. (Ex 12÷ 3 =4) 3 is the divisor QUOTIENT : is the result in a division problem (Ex. 12÷3= 4 ) 4 is the quotient

8. Learning Objective: SWBAT multiply and divide integers. Key concept: Multiplying integers: The factors have the SAME signs. The product is POSITIVE The factors have DIFFERENT signs. The product is NEAGTIVE. Dividing Integers: The dividend and the divisor have the SAME signs. The quotient is POSITIVE. The dividend and the divisor have DIFFERENT signs. The quotient is NEGATIVE .
