1. The problem is to understand how to borrow from the tens place in subtraction. 2. Borrowing is used when the digit in the ones place of the number you are subtracting from is smaller than the digit in the ones place of the number you are subtracting. 3. The rule is: you take 1 ten (which equals 10 ones) from the tens place and add it to the ones place. 4. For example, if you have to subtract 8 from 3 in the ones place, you cannot do it directly because 3 is less than 8. 5. So, you borrow 1 ten from the tens place, reducing the tens digit by 1. 6. Then you add 10 to the 3 in the ones place, making it 13. 7. Now subtract 8 from 13, which equals 5. 8. This borrowing process allows subtraction to be done correctly when the top digit is smaller than the bottom digit in a place value. 9. Always remember to reduce the tens place by 1 when you borrow 10 to the ones place.
