In class today we learned how to solve questions that has to do with adding and subtracting more than two numbers, like the question (-10)+(-8)+(+6)-(+2).
To solve this question you must first change the question so that all the operations are all addition.
Now you combine all the positive integers in one group and the negative integers in another group.
Now you add up the total of each group to get the answer.
If you have a zero pair in a question like that then do this.
That is how you get the answer for this type of integer question. These are some of the questions and answers for page 48 and page 49.
These are some of the questions from page 48.
22) (-5) + (-3) - (+4) = -12
27) (+5) - (+3) - (+2) + (-1) = -3
These are some of the questions from page 49.
7) (-8) - (-3) - (-4) = -1
10)(-8) - (+5) + (+3 = -16
18) (-2) - (-1) + (0) = -1
Sorry if I did anything wrong, just comment if I did.
