To solve this subtraction problem, we will follow these steps:
Step 1: Set up the subtraction vertically.
Step 2: Subtract the numbers in the ones column.
Step 3: If needed, borrow from the tens column.
Step 4: Subtract the numbers in the tens column.
Let's work through each step:
Step 1: Set up the subtraction vertically:
Step 2: Subtract the numbers in the ones column.
We have in the ones position on the top number and on the bottom number. Since is less than , we need to borrow 1 from the tens place of the top number.
After borrowing, the in the tens place becomes , and we add to the ones place, transforming into . Now, subtract from :
Step 3: Subtract the tens column. Now, after borrowing, we have (since ) in the tens position, minus from the tens place of the bottom number:
Step 4: The final result is obtained by putting together these results. The subtraction yields:
Therefore, the solution to the problem is .

You can't subtract a larger number from a smaller one in subtraction! That's why we need to borrow from the tens place to make the ones digit bigger.
Borrowing means taking 1 ten (which equals 10 ones) from the tens place and adding it to the ones place. So 2 becomes 12, and 6 becomes 5.
Think of it as trading: you give up 1 from the tens place (6 becomes 5) and get 10 in the ones place (2 becomes 12). It's like trading a 1 bills!
If , you made an error! Go back and check: Did you borrow correctly? Did you subtract the right digits? Double-check each step.
No! You only borrow when the top digit is smaller than the bottom digit. If 62 - 31, you wouldn't need to borrow since 2 > 1.
