Add to Integer Notes: ***MULTIPLICATION*** SAME Signs: The product is always POSITIVE D IFFERENT Signs: The product is always NEGATIVE ***DIVISION*** SAME Signs: The quotient is always POSITIVE D IFFERENT Signs: The quotient is always NEGATIVE

Triangle Method + - -

Guided Practice in Notes 5 · (-3) = _______ 5·3= 15 5 is positive and 3 is negative Different Signs, the product is negative = -15 -4·-6= _______ 4·6=24 4 is negative and 6 is negative Same Signs, the product is positive = 24

Examples: 12(-10)= -5·9 = -8 * (-7) = (6)(-8)(2) =

Based on the Rules: Examples: (- )= -10 (- )(- )= 12

Guided Practice in Notebook 15 ÷ (-3) = 15÷3= 5 15 is positive and 3 is negative Different signs, the quotient is negative =-5 -35÷(-5)= 35÷5=7 35 is negative and 5 is negative Same Signs, the quotient is positive = 7

Examples: 25 ÷ (-5) = −100 (−10) = −16 4 = −27 3 =

Based on the Rules Examples: _____ = -2 - - _____ = 4

Sponge Bob’s watch is water resistant up to -10 feet Sponge Bob’s watch is water resistant up to -10 feet. Patrick’s watch is water resistant up to 9 times the depth of Sponge Bob’s watch. Patrick’s watch is water resistant to what maximum depth?

At midnight the temperature is 10°C At midnight the temperature is 10°C. If the temperature rises 4°C per hour, what is the temperature at 6 am? How long Is it from Midnight to 6 am? How much does the temperature rise each hour? 6 hours +4 degrees (6 hours)(4 degrees per hour) Add this to the original temp. = 24 degrees 10° + 24° = 34°C

Addition: If the signs are the same, add the numbers together and use the same sign for the sum. If the signs are different, subtract the absolute values of the numbers and take the sign of the number with the larger absolute value. Example: -7 + -9 = 3 + (-4)= Subtraction: Add the opposite (change to an addition problem and then follow rules for addition. KEEP the 1st Number Subtraction becomes ADDITION Take the OPPOSITE of the second number Example: -7 – (-9) = 3 - (-4)= Multiplication: same signs, positive product Different signs, negative product + Example: - - -7 (-9) = 3 (-4)= Division: same signs, positive quotient Different signs, negative quotient + Example: - - -72 /-9 = 48/ -4=
