In subtraction, "ungroup" refers to the process of breaking apart a larger number to facilitate easier calculation. For example, when subtracting 7 from 12, you might ungroup 12 into 10 and 2, allowing you to subtract 7 from 10 first and then deal with the remaining 2. This technique is particularly useful in teaching elementary math, as it simplifies the process and helps students understand the concept of borrowing in multi-digit subtraction.
