## Two Digit Subtraction

#### Grade 2 Operations - 2.NBT.B.5

What is Borrowing in Subtraction? Do you the concept of carrying in addition problems in mathematics, where you put/add an extra value to the number to balance the answer? Borrowing or regrouping in subtraction is just the opposite of this idea. In subtraction, you borrow value from the next biggest digit in the left column to support the digit, which is smaller in value and get an answer for that digit. Some of you might hear the term regrouping. Nevertheless, borrowing and regrouping are the same. The extra amount that you take from the left column is known as the borrowed amount or digit. For example; 4 - 2 = 2 (this required no borrowing or regrouping). 36 - 9 = 27 (this required borrowing or regrouping from the digit 3). The borrowing or regrouping can also move to the next two or three digits in line. For instance, in this example, 624 - 7 = 617, we got this answer by borrowing value from 6 rather than 2. Therefore, it is not certain where the borrowed value lies. These worksheets and lessons will teach students how to find the difference between double digit numbers.
