Today in class Mr.Harbeck gave us a green booklet,and we tackled about adding and subtracting integers in standard form. For our homework Mr.Harbeck assigned us to do the part 1 (1-20) and part 2 (even numbers only).
In some cases in the part 2 , you should re-write the question first and then add the opposites
and you must also have to remove the "diapers" or parenthesis or something like Mr.Harbeck said...
e.g.
1.) 8 - (-7) + 3 - (-5) = ?
have8 owe owe7 have3 owe owe5 = ?
8 + 7 + 3 + 5 = 23
have8 have7 have3 have5 = have23
but in part 2 you only have to do the even numbers.....
2.) 5 - (-8) - (7) + 5 = 25
4) 5 - 2 - (-7) - (-3) = 13
6) -7 - (-5) - (-7) - 8 = -3
8) -7 - (-5) - (5) + 8 = 11
10) - (-2) - (-6) - 15 = -7
12) -2 - 3 + 4 - 6 = -7
14) 2 - 7 - 8 = -13
16) 3 - 8 + 9 = 2
18) - 20+ (-8) - 4 - (-10) = -6
20) -100 - (-100) + 50 - (-50) = 100
22) -10- (-10) -1 =1
24) - (-5) + 9 - 20 = -6

But for number16
you wrote 3 - 8 + 9 = 2( actually 4)
which the question is suppose to be
3-9+8=2.
