Dividing Integers Scribe #2

Have ----->(+8)  ÷ (+4) <---- Groups
There are two ways to solve this problem:
1) Share (8) into 4 equal groups
++ ++ ++ ++
2) How many groups of 4 are in 8?
++++ ++++

(-8)  ÷ (-4) = 
Share (-8) into (-4) equal groups
We cant do that because we cant share negative into another negative. 
How many equal groups of (-4) are in (-8)
---- ----
(-8) ÷ (+4) =
Share (-8) into 4 equal groups
-- -- -- -- 
How many groups of (-4) are in (-8)?
(+8) ÷ (-4) =
Share (+8) into (-4) equal groups
How many groups of (-4) are in (+8)?
-2 x -4 = 8
^This is called Multiplicative Inverse ^

  1. Good job, very easy to understand and simple. maybe you can make your size a little bigger so its more visible and everything we learned is there also add a video.

  2. Good scribe, you kept it simple and easy. You could have also reminded us about the sign rule and how it's still used in Division, but other than that I liked the scribe.
