    Commutative:
    You finished your math homework, and then later you finished your English homework. Tomorrow you finish your English homework and then math homework.

    Associative:

  4. Commutative :
    Writing with a pencil first and pen later is the same as writing with a pen first and a pencil later. This is the same because no matter the order, you are still using both pen and pencil.

    Associative :
    Our class received an assignments. First, Bob works with Sam and Charley works alone. Next, Bob works alone and Sam and Charley work together. This is the same because even though the grouping is different, they receive the same results of finishing the assignments.
    (b+s) + c = b + (s + c)

    Reflexive :
    There is an algebra book. An algebra book is an algebra book.
    a = a

    Symmetric :
    A car (a) equals to its parts (b). A car’s parts (b) equals to a car (a).
    a = b , then b = a

    Closure :
    There is water (a). There is also a sprayer (b). Adding these together makes a sprayer with water in it (c).
    a + b = c

    Transitive :
    Mukund’s shoe size (a) equals Victoria’s shoe size (b). Victoria shoe’s size (b) is equal to Bob’s shoe size (c). Therefore, Mukund’s shoe size (a) is equal to Bob’s shoe size (c).
    a = b, b = c, a = c

    Distributive :
    Bob has a job of making computers. He earns $50 an hour (a). On the first day, he works for 2 hours (b). On the second day, he works for 3 hours (c). Another day, he works 5 hours in a row (d). Therefore, he earns 50(2+3) which is the same as 50*2 + 50*3. In total. Bob earns $250. In the other day, he earns 50(5), which is the same as 50(2+3).
    a(b+c) = ab + ac

    Identity :
    There is a charger that doesn’t work (a). The macbook has 0% charged (b). You try to charge it, but the charger doesn’t work. The charge of the macbook does not change. Therefore, 0 + 0 = 0.
    a + 0 = a

    Property of Opposites
    Fire is a and water is -a. If you add them together, they become nothing.
    a + (-a) = 0 or -a + a = 0

    Property of Opposites of a Sum
    Ashley (a) breaks her macbook. Bob (b) also breaks his macbook. They go to the IT Office together, but the IT person says that it is not able to be fixed until the next week. Later, they go separately but the IT office says the same thing. Therefore, being together or being individually doesn’t matter. You still get the same outcomes.
    -(a+b) = -a + (-b)

You eat the Chocolate syrup by itself, then you mix the Strawberry Syrup with the ice cream and eat it. In the end, the order didn’t change, but the way you mixed(grouped) the foods, it came out as the same outcome; you ate everything!
    Reflexive: Look on the surface of water
    Symmetric: JoeBob is standing in front of the mirror. If JoeBob and mirror JoeBob is the same, then Mirror JoeBob=JoeBob. AB=BA
    Closure: Mix Pasta Noodles with Tomato Sauce. Then, there is only one specific outcome. (Tomato Pasta)
    Transitive: Tomato=təˈmātō. Tomato=Fruit təˈmātō=Fruit.
    Distributive: There was a kid who had chocolate, and candy. Then, he gave some to one of his friends. However, he had other friends too, that did not get the candy, so he gave them too. A(B+C)=AB+AC (A=Candy and Chocolate)

    Property of Opposites: (+)Marker + Board Eraser(-)=0
    Property of Opposite of a Sum: There was a bundle of happy kids, and they were influenced by a bad man. They also turned bad. There were also a few bad kids with some more bad kids. They went together, and in the end, they are still bad. Bad=(-) Happy=(+)

  6. Math Project making videos for 10 properties that we learned. Kevin Chyun B Block

    Commutative Property: Kevin wore shoes A at 9:00am and shoes B at noon two days ago. Yesterday, he wore shoes B at 9:00am and shoes A at noon.

    Associative Property: My friend was mad and he threw a crumpled piece of paper first, a notebook second, and pencil last. Later, when he got mad again, he threw a notebook first, a pencil second, and a crumpled piece of paper last.

    Reflexive Property: Alex was a handsome guy but he had an awkward personality. He always looked at himself in the mirror every day. When he looked in the mirror, he saw himself, which is the reflexive property.

    Symmetric Property: Kevin visited Busan riding in a car on the highway. Then, right after Kevin arrived in Busan, his friend, Bob, went to Seoul. After 10 days, Bob needed to go to Busan because of his business problem so he proceeded his way. After Bob arrived, Kevin went back to Seoul to meet his friends at KIS.

    Identity Property: Jeremy was the most famous boy at KIS so everybody in middle school knew him and said hi to him whenever they saw him. Also, Jeremy was friends with everybody se he couldn’t get anymore friends at KIS. a (number of friends that Jeremy has) + 0 (he can’t get anymore friends)= a (Jeremy’s current number of friends)

    Transitive Property: In 2011, Kevin bought a macbook pro which is the second best computer out of three lap tops, and is the same one that Eric has. Eric has the same computer as Ryan, who has the computer that is the second best. This means that Ryan and Kevin have macbooks that have same versions!

    Distributive Property: Kevin gave a cup of water to flower A and flower B. This means that flower A and flower B both got water from Kevin.

    Closure Property: If I add ice to a cup of water, there is a cup of water with ice in it.
    Ice + a cup of water = A cup of water with ice in it

    
Property of opposites: Mr. Jobe, one day got a disease that made him unable to speak after he visited London to watch the Olympics. When he came back to Korea, he went to the hospital and got a shot in his mouth. After this shot, Mr. Jobe could speak again without any problems.

  7. Commutative Property of Addition- a+b=b+a
    On Monday Joe studied for Algebra for one hour, then studied Science for one hour. On Tuesday Joe studied Science for an hour, and then studied Algebra for an hour. He got the same amount of studying time on both days.

    Associative Property of Addition- (a+b)+c=a+(b+c)
    Bob, Mom and Jack are going to the park. Bob holds hands with Mom, and Jack walks alone. After 5 minutes, Bob walks alone, and Mom holds Jack’s hand. The order they stand in does not change but the grouping (holding hands) does change, and these two cases are the same because all three people end up in the park.

    Distributive Property of Addition- a(b+c)=ab+ac
    Bob was in Mr. Patrick’s science class. In class, Bob mixed coke and sprite first, and then mixed the two liquids in his first experiment. On his second experiment, he boiled each coke and sprite. He mixed them after he boiled them, and he found out that the two mixtures were the same in amount and taste.

    Reflexive Property of Equality- a=a
    Jin mo took a picture of himself out of boredom and uploaded on facebook. His friends saw Jin mo’s picture and said, “Hey, that’s Jin mo!” Thus, the Jin mo in the picture looks the same as his self in real life.

    Great written examples! Very thorough work.
