Borrowing subtraction is a technique used in arithmetic when subtracting larger digits from smaller ones in a multi-digit number. When the top digit is smaller than the bottom digit in a given place value, you "borrow" 1 from the next left place value, effectively reducing it by 1 and adding 10 to the current place value. This allows you to perform the subtraction correctly. For example, in the subtraction 42 - 27, you would borrow from the 4 in the tens place to subtract 7 from 12 in the ones place.
