    1. 1. Study Guide By: Yuhan T.
    2. 2. Adding NegativesExample Questions: (-7) + (-8) , (+7) + (-9) etc.Problem: (-6) + (-8)How to:First, the key to all operations with negatives is tosimplify. If you don’t, you would easily get confusedwith unnecessary things. Remove the brackets:(-6) + (-8) > -6 + -8Then remember, if there is a + and a - signtogether, remove the +.-6 + -8 > -6 - 8Then calculate:-6 - 8 = -14
    3. 3. Adding Negatives 2Problem: (+8) + (-4)How to:Simplify; remove any unnecessary signs:(+8) + (-4) > +8 + -4+ and a - sign together, remove the + sign.+8 + -4 > +8 - 4Calculate:+8 - 4 = 4
    4. 4. Subtracting NegativesExample Questions: (-6) - (-7) , (+6) - (-4) etc.Problem: (-4) - (-7)How to:First, simplify.(-4) - (-7) > -4 - -7After that, if there is two - signs together, removeboth of them and turn it into a + sign.-4 - -7 > -4 + 7Calculate:-4 + 7 = 3
    5. 5. Subtracting Negatives 2Problem: (-3) - (+8)How to:Simplify,(-3) - (+8) > -3 - +8- and + sign together, turn it into a - sign only.-3 - +8 > -3 - 8Calculate:-3 - 8 = -11
    6. 6. Multiplying NegativesExample Questions: (-6) x (-3) , (+5) x (-9) etc.Problem: (-7) x (-2)How to:Simplify, remove the brackets.(-7) x (-2) > -7 x -2Important rule, when it’s a negative times anothernegative, the product is a positive.Calculate with rule.-7 x -2 = 35
    7. 7. Multiplying Negatives 2Problem: (-6) x (+4)How to:Simplify.(-6) x (+4) > -6 x 4Rule, if it’s a negative times a positive (or vice-versa) the product must be a negative.Calculate with Rule.-6 x 4 = -24
