How to explain subtract a two-digit number from a three-digit number: word problems to your student
30 October 2026
When children start working with word problems, subtracting a two-digit number from a three-digit number can seem tricky. Using a real-life example helps them see how subtraction works in everyday situations.
Example question
A shop had 245 pencils. It sold 38 pencils in one day. How many pencils are left?
Step 1: Write the number sentence
245 - 38 =?
Step 2: Subtract the ones
5 - 8 cannot be done, so borrow 1 ten from the tens.
Now 15 - 8 = 7
Step 3: Subtract the tens
Since we borrowed 1 ten, the tens digit is now 3 (4 - 1 = 3).
3 - 3 = 0
Step 4: Subtract the hundreds 2 - 0 = 2
Answer:
There are 207 pencils left.
After seeing this example, your child will recognise the steps involved in breaking down a subtraction problem with borrowing. They are now ready to practise similar word problems and build their confidence.
