ADDing and SUBTRACTing are Both Based on DIFFERENCE.
In the video my brain starts to malfunction at times, and we struggle to explain this idea. It's a hard idea! It actually is! After a few tries, explaining it different ways, maybe it finally makes sense. *Maaaybee*??
If not, here is one more BONUS explanation in different words not found in the video:
In a basic problem with MINUS, you will know the bigger number, and you will know the difference, and so then you will need to figure out the smaller number.
In a basic problem with PLUS, you will instead know the smaller number, and you will know the difference, and so then you will need to figure out the bigger number.
Get it?
Got it?
Uhhhhmmmmmmm, maybe?
I hope so!
