• why is 500 -300 200
• because 500-300=500-400=100+100
• is confusing I don't get it. I would expect an 83 there tho
• 853 - 200 - 53 - 30 is the same thing as 853 - 200 - 83.
-53 - 30 = -(53 + 30)
= -(83)
It's confusing that 83 isn't directly written, but not every problem will be completely straightforward. Does this help?
• how you writea lot

• can you do 5,978,509 times 300
• 5,978,509 times 300 is 1793552700
• umm is confised can u help me
• Question-
What if you needed to subtract more than 1, would you do the same thing or different?
• Can you guys help me on please?
• Sure! It's actually the same thing and it's easier on the brain. So, if you add 53 and 30, then you would get 83, right? That's exactly what the guy was literally talking about!!
• how do i do the math problem 639-127 is the same as blank -130
