This understanding involves subtracting one three-digit whole number from another when each minuend digit is at least as great as the corresponding subtrahend digit, so hundreds, tens, and ones can be subtracted independently according to place value. The difference can be represented in standard or expanded form, and accurate alignment of digits is essential; cases requiring regrouping, including borrowing across place values, are outside this scope.
