Question

If you had to subtract 426 from 913 how many times would you need to regroup ?

Answer 1

  913

 - 426

487 would be your total but your question is how many times we would have to regroup, so.

First, you would have to borrow from the 1 because 3 is smaller then 6. Second, you would have to borrow from the 9 because you can't take 2 from 0. So there you would have to regroup twice to work this problem.

Hope that helps you. :-)

Answer 2

Well u would have to subtract the other way around so 913-426=487 but since it is the other way around (426-913)  our answer 487 would be negative so our answer would be -487 u would regroup 3 (three) times hope this helped !
