3-Digit Subtraction

Subtraction is the process of finding the difference between two numbers. When subtracting 3-digit numbers, it's important to align the numbers properly according to their place value: hundreds, tens, and ones.

Here's an example to illustrate 3-digit subtraction:

Subtract 426 from 753.

First, align the numbers vertically:

   753
-  426
------

Start by subtracting the ones place: 3 - 6. Since 3 is smaller than 6, we'll need to regroup. Borrow 1 from the tens place, making the tens place 5 instead of 4, and add 10 to the ones place, making it 13 instead of 3.

   753
-  426
------
   3 (13-6)

Next, move to the tens place: 5 (after regrouping) - 2. 5 is larger than 2, so we can subtract directly.

   753
-  426
------
  35

Finally, subtract the hundreds place: 7 - 4. Again, 7 is larger than 4, so we can subtract directly.

   753
-  426
------
 327

So, 753 - 426 = 327.

Always remember to double-check your subtraction by adding the difference to the smaller number to ensure that the result is the larger number.

With practice, you can become proficient in subtracting 3-digit numbers!
