When you you multiply when do you need to regroup?
You need to regroup when you add the numbers together and they add up to a number that is ten or more. For example: 1 164 +518 _____ 682 If it is over ten, take the first digit of the number and put it above the next number. Then, add that number onto the sum of the other digits underneath it.

What is 99.998 rounding to the tenth place?
99.998 rounding to the tenth place is 100. The hundredths digit is a 9, so you round up to 0 and regroup it to the tenth. The tenths digit is a 9 and regrouping would make the tenths digit a 0 too. This happens with the ones and tens digit. All the 9's regroup to 0's making the answer 100.
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!
