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) =

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

-- -- -- --

(+8) ÷ (-4) =

-2 x -4 = 8

^This is called Multiplicative Inverse ^

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.

ReplyDeleteGood 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.
