u just regroup the whole number ( ex. 7 would be 7 over 7)
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.

There is no such number. You can add 456000 or 456878322168000 or even 1581687671173873681773618733111
I take this question to mean what number when added to 457 will yield 999. In this case it is 542.
460
