Best ResponseYou've already chosen the best response.3I think this wants to show you how a negative number moves left and positive to the right...so.. plus a negative number is the same as just subtraction 3  5

Best ResponseYou've already chosen the best response.3it is saying +(move right) by (5) which itself moves left

Best ResponseYou've already chosen the best response.3no just remember, a + (b) = a  b plus a negative is subtraction

Best ResponseYou've already chosen the best response.3if you add a negative number to a value on the numberline, you move left, same as if you just had subtracted it

Best ResponseYou've already chosen the best response.3the other one is minus a negative number, same as just addition a  (b) = a + b

Best ResponseYou've already chosen the best response.0i really need to get a good grade on this test. i did the number line and went from 0 to 3 then i went left 5 times and i got 2

Best ResponseYou've already chosen the best response.0i started at 0 and went right till i got to the number 3. then i went left 5 times but started at 3 instead of 0 and i got 2. Is this right or wrong?

Best ResponseYou've already chosen the best response.3the upper one is just showing the distance between 3 and 2, not sure what you have to include on your graph

Best ResponseYou've already chosen the best response.3oh they want you to start at zero? then to show 3  5 = 2 ... start at zero, move +3, then move 5, end on 2

Best ResponseYou've already chosen the best response.0in the original problem the 7.3 is positive, why in 1. he wrote it was negative

Best ResponseYou've already chosen the best response.0In the original problem 7.3 is positive, when Allen wrote it as commutative and additive inversion, he wrote it as a negative. That was one mistake. Another mistake was that since 3.7 is not negative, he does not need an extra set of parentheses for 7.3. instead of (−4.5 + (−7.3)) + (4.2 + 5.6) it should be (4.5 + 7.3) + (4.2 + 5.6). Since he messed up with all that, the way he simplified his answer is wrong too.

Best ResponseYou've already chosen the best response.3why are you saying 7.3 is positive? −4.5 + 4.2 + 5.6 − 7.3 was given

Best ResponseYou've already chosen the best response.0isnt that infront of 7.3 a subtraction

Best ResponseYou've already chosen the best response.3all the numbers look good to me except for the last simplifying step where he subtracted instead of added.. if the original prob is copied wrong, then i guess that too, or maybe the additive inverse thing as well...
