How to Subtract Multiples of 10 Easily (With Examples)
FAQs on Subtracting Whole Tens – Class 4 Maths Practice Worksheet
1. What are whole tens in subtraction?
Subtracting whole tens is a method where you subtract a number that is a multiple of 10 (like 10, 20, 50, etc.) from another number. This technique simplifies subtraction for Class 4 students by focusing on the tens place value, making calculations quicker. For example, in 80 – 30, you are simply taking 3 tens away from 8 tens to get 5 tens, or 50.
2. How do you subtract tens easily?
You can subtract tens easily by using mental maths strategies that focus on place value. This free worksheet for Grade 4 Maths teaches several easy steps for subtracting multiples of 10.
- Identify the tens: In a problem like 60 – 20, identify that you are working with 6 tens and 2 tens.
- Subtract the tens digits: Simply subtract the digits in the tens place (6 – 2 = 4).
- Add the zero back: Since you were subtracting tens, add a zero to your answer, making it 40.
- Visualise: Use tools like a number line to count backwards in jumps of 10.
3. Why is it important to teach the subtraction of whole tens in Class 4?
Teaching the subtraction of whole tens is crucial in Class 4 because it builds a strong foundation for more complex maths.
- It develops number sense and reinforces the concept of place value.
- It promotes mental maths strategies, helping students solve problems faster without pen and paper.
- It prepares students for advanced topics like subtraction with borrowing and multi-digit subtraction.
- It improves overall confidence in handling subtraction sums for Class 4.

7. How does this worksheet help in building mental maths skills?
This worksheet is specifically designed to strengthen mental maths strategies for Grade 4 students. By focusing on subtracting multiples of 10, it encourages children to move beyond finger counting or column subtraction. Regular practice helps students automatically recognise patterns (like 70-20 is just 7-2 in the tens place), which builds calculation speed and accuracy for all primary maths subtraction.
8. What is the best way to use this Class 4 maths worksheet for practice?
For the best results, use this downloadable worksheet as a tool for concept reinforcement after the topic has been introduced in class.

- Encourage them to complete the fill-in-the-blanks subtraction problems first.
- Use the number line subtraction activity to help with visualisation if they get stuck.
- Finally, use the included answer key to review their work together.
9. Is this worksheet suitable for the CBSE syllabus?
Absolutely. This CBSE subtraction worksheet for Class 4 is created by subject-matter experts and is fully aligned with the core concepts outlined in the NCERT and CBSE curriculum. It focuses on foundational skills like place value and subtraction without borrowing, which are essential parts of the Class 4 maths syllabus.
10. How does subtracting whole tens relate to place value?
Subtracting whole tens is directly built on the concept of place value. It teaches students that a number like 70 is composed of '7 tens' and '0 ones'. When solving 70 – 20, a student with good place value understanding knows they only need to manipulate the tens column. They mentally perform 7 tens – 2 tens = 5 tens, and then convert '5 tens' back to the number 50.
