To solve this subtraction problem, we need to subtract from . We'll approach it step-by-step:
Begin with the rightmost digits: Subtract from . Since is smaller than , we must borrow.
Borrow from the tens place: Reduce the next digit left (0 in the tens place) by 1. However, since it's , continue borrowing from the hundreds place.
The hundreds place reduces to , making the tens . Borrow from these , making the tens and increasing the units place to 12.
Now, subtract: .
For the tens place, subtract from (after adjustment): .
Finally, the hundreds place: Subtract from , giving .
The subtraction gives us the number .

You're right! Since 2 is smaller than 7, you need to borrow from the next column. This is like trading a ten for ten ones, making the 2 become 12.
When the tens digit is 0, you can't borrow from it directly. Instead, keep moving left until you find a non-zero digit to borrow from, then work your way back.
Add your answer to the number you subtracted. If you get the original number back, you're correct! For example: ✓
Great question! The 6 in hundreds becomes 5 (borrowed 1), the 0 in tens becomes 10 then 9 (received 1, then lent 1), and the 2 in ones becomes 12 (received 1 from tens).
Yes! You could use mental math strategies like: . But vertical format helps you see each step clearly.
