What regroup mean in subtraction?
Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6), you have to "regroup" and subtract on from the top digit to the left of the digits your working with and then add a ten to the top digit your working with. Finally, you subtract. (645-9=630+15-9) Hope that makes sense!

How do you subtract using regrouping?
"Regrouping" is a more modern word for "borrowing". When subtracting with decimals, if you are trying to subtract a larger digit from a smaller digit, you "regroup" the next digit to the left by taking one away from it and adding 10 to the number you are subtracting from. Example 84 - 19 _____ You can't subtract 9 from 4, so you take one away from the next digit over (the 8) and add 10 to the 4. 14 - 9 is 5 in the ones digits 7 - 1 is 6 in the tens digits Now if you are subtracting mixed numbers, the regrouping process is essentially the same, except that instead of always regrouping by tens, we regroup by the denominator size. 8 1/5 - 3 3/5 ______ We can't subtract 3/5 from 1/5, so we regroup one unit from the 8 into 5 fifths. 7 6/5 -3 3/5 _______ 4 3/5 It is very easy when you get some practice doing it.
