Reymel's Integer Post

Column 3 Questions (Q.)

Q. (-4) + (+4) = 0
       owe 4 and have 4
I got this answer using zero pairs.

O = Positive
O = Negative

OOOO     Will cancel each other out, which gives us 0.
OOOO


 Q.(-6) + (-7) = (-15)
     owe 6 and owe 4
I got this answer by looking at the question first. It's just like an addition problem but with negative integers.

O = Positive
O = Negative

OOOOOO     add these together and you get 15 negative blue circles in total.  
OOOOOOO          


Q.(+7) + (-9) = (-2)
      have 7 and owe 9
I got this answer by getting rid of the plus (+) sign and the brackets ( ). That would give me this equation, "+7-9" which is subtraction. Seven minus nine will give me negative two. Or if I use a zero pair, 2 negatives will be left.        

O = Positive
O = Negative

OOOOOOO  Zero pair first, then the answer.
OOOOOOO  (OO) 
                       answer
