• do you have more methods that you think you could share with us?
• You could simply countdown to subtract...
But that's a lot of unnecessary effort...
• Can someone explain me what the easier way to do this
• there are many ways to do it! I will explain two ways to do it. first subtract 6 hundreds from a thousand. then, see how much you need to subtract to get to 528. the amount you subtracted is adding what we just did. since 528 is the starting point and 1000 is the ending point, they would not be included. have a blessed, wonderful day and hope it helps!😊😄
• how do you use the box method?
• how do you subtract 340,567-68,415
• do you have any ways to solve 6 and 7 digit problems?
• Yes, what I do is I put it up and down so it should look like this
(number)
-(number)
------------
I hope this new found information helps you!
• Can we also subtract millions? Billions? Trillions? Quadrillions?
• yes. you may not be able to do it in your brain, but you can do it on a paper.
• Would it be correct to say that the number you're subtracting from should be greater than the number you're subtracting, so, all the digits should be greater?
• no need of it! you can keep any number less than the one below it. but if you don't know the Regrouping lesson and video, then you can keep all numbers greater than the one below it. hope it helps!
