THNX UR A REALLLY GOOD TEACHER
Thanks man! Really is gonna help me on my quiz.
Thanks animallover…but that’s actually how you multiply integers, not add and subtract. -9 +(-9) is actually -18, not positive 18.
READ THIS ITS WAY BETTER FOR LEARNING. YOU WILL GET IT RIGHT AWAY.when you see a question like: +9 – (-4)=
see how there is 2 – next to eachother, that means its +, just forget about the + on the left, never look at it. always look at the right +/-
LOOK HERE!!!.
+ + = +
- – = +
- + = -
+ – = -
What you see up there
^
is alway on the right. its not the first part of the question like -9 + (-9)
^never look at that -
look at the next + and –
sooo + – = – so the question equals18
THANK YOU SO MUCH!!! My son finally got it. I just wish I would have found your video sooner.
The best educational video ever although you should make it more exciting E.G. Robber vs police or food vs people to eat it!
negative kitties! poor kitties
omg so gelpful! thx alot
a suggestion for you:
your hand doesn’t let us see what you’re writing sometimes. Specially when you teach “two negatives make a positive”.
Very good video though, I showed my students.
I’m in college algebra and I have to do this sometimes still lol.
Thanks for this method, it unscrambles the whole thing.
