Addition and subtraction are fundamental math skills that every student must master. These operations are used in everyday life, from counting money to measuring ingredients for a recipe. In Class 4, students learn more advanced techniques, such as carrying and borrowing, solving word problems, and dealing with larger numbers. This topic provides a collection of addition and subtraction questions for Class 4 students, along with explanations to help them understand the concepts better.
1. Understanding Addition and Subtraction
Before practicing questions, let’s review the basics of addition and subtraction.
Addition
Addition is the process of finding the total of two or more numbers.
- Example: 345 + 678 = 1,023
Subtraction
Subtraction is the process of finding the difference between two numbers.
- Example: 876 – 452 = 424
2. Simple Addition and Subtraction Questions
A. Two-Digit Addition
- 45 + 32 = ?
- 67 + 89 = ?
- 29 + 71 = ?
B. Two-Digit Subtraction
- 78 – 46 = ?
- 95 – 27 = ?
- 63 – 19 = ?
3. Three-Digit Addition and Subtraction Questions
A. Three-Digit Addition
- 234 + 567 = ?
- 789 + 124 = ?
- 356 + 431 = ?
B. Three-Digit Subtraction
- 987 – 654 = ?
- 425 – 214 = ?
- 678 – 329 = ?
4. Addition and Subtraction with Carrying and Borrowing
A. Addition with Carrying
When the sum of two digits in a column is greater than 9, we carry over the extra value to the next column.
- 476 + 589 = ?
- 268 + 743 = ?
- 835 + 679 = ?
B. Subtraction with Borrowing
When subtracting, if the top digit is smaller than the bottom digit, we borrow from the next column.
- 705 – 389 = ?
- 924 – 658 = ?
- 871 – 492 = ?
5. Word Problems on Addition and Subtraction
A. Addition Word Problems
- Rohan has 215 marbles. His friend gives him 148 more. How many marbles does he have now?
- A bookstore sold 423 books in the morning and 297 books in the evening. How many books were sold in total?
- There are 625 students in one school and 378 in another. How many students are there in both schools?
B. Subtraction Word Problems
- An apple tree had 562 apples. A farmer picked 348 apples. How many apples are left?
- A library has 923 books. 465 books were borrowed by students. How many books are left in the library?
- A car factory produced 1,250 cars in a year. They sold 978 cars. How many cars remain unsold?
6. Mixed Addition and Subtraction Questions
Students should be able to switch between addition and subtraction to solve problems efficiently.
- 657 + 389 – 245 = ?
- 872 – 349 + 221 = ?
- 529 + 318 – 417 = ?
7. Challenge Questions for Class 4
A. Large Number Addition
- 4,768 + 3,259 = ?
- 9,835 + 6,472 = ?
- 7,592 + 8,183 = ?
B. Large Number Subtraction
- 8,924 – 5,378 = ?
- 6,150 – 4,762 = ?
- 9,781 – 7,493 = ?
C. Puzzle Question
- A train has 738 passengers. At the next station, 264 passengers get off, and 189 new passengers get on. How many passengers are now on the train?
8. Tips to Solve Addition and Subtraction Quickly
Here are some useful tricks to help students solve problems faster:
A. Addition Tricks
- Start adding from the rightmost digit (ones place).
- Use rounding to simplify numbers before adding.
- Break large numbers into hundreds, tens, and ones to make adding easier.
B. Subtraction Tricks
- If the top number is smaller, borrow from the next column.
- Check answers by adding the difference back to the subtracted number.
- Use mental math for simple problems.
Addition and subtraction are essential math skills for Class 4 students. By practicing varied types of questions, including basic sums, word problems, and challenge exercises, students can improve their accuracy and speed. The key is to practice regularly and use strategies like carrying, borrowing, and estimation to make problem-solving easier.
