How to Add and Subtract Integers Easily with Examples and Tips
FAQs on Addition and Subtraction of Integers Worksheets for Grade 5
1. What are the basic rules for adding and subtracting integers?
To add and subtract integers, you must follow specific rules based on whether the numbers are positive or negative. These integer rules are fundamental for correct calculations.
- Adding Same Signs: Add the numbers and keep the same sign. For example, 5 + 3 = 8 and (-5) + (-3) = -8.
- Adding Different Signs: Subtract the smaller number from the larger number (ignoring the signs) and use the sign of the larger number. For example, -8 + 3 = -5.
- Subtracting Integers: Change the subtraction operation to addition and change the sign of the second number (add the opposite). For example, 6 - (-2) becomes 6 + 2, which equals 8.
2. What age group is this addition and subtraction of integers worksheet for?
This worksheet is specifically designed for Grade 5 students who are learning about integer operations for the first time. The problems and activities are aligned with the standard Class 5 maths curriculum, making it suitable for children around 9-11 years old.
3. How do you add and subtract integers using a number line?
A number line provides a visual method to perform the addition and subtraction of integers. This approach helps in understanding the movement between positive and negative numbers.
- Starting Point: Always begin at the position of the first number in the equation.
- Adding a Positive Number: Move to the right on the number line.
- Adding a Negative Number: Move to the left on the number line.
- Subtracting a Positive Number: Move to the left on the number line.
- Subtracting a Negative Number: Move to the right on the number line.

7. Is this addition and subtraction worksheet for Class 5 printable?
Absolutely. This worksheet is available as a free printable PDF, making it easy to use for both classroom and at-home learning. You can download the file and print it on standard paper, providing a hands-on resource for students to complete their maths practice.
8. Why is practising with an integer operations worksheet important for Grade 5 students?
Practising with an integer operations worksheet is crucial for Grade 5 students as it builds a strong foundation for future maths. It helps students to:
- Gain confidence in working with negative numbers.
- Master the fundamental rules of addition and subtraction with a new set of numbers.
- Develop the critical thinking needed for more complex topics like algebra and geometry.
- Improve overall number sense beyond just whole numbers.
9. How do you solve problems with mixed addition and subtraction of integers?
To solve problems involving mixed addition and subtraction of integers, you should perform the operations sequentially from left to right. It is helpful to rewrite subtraction as adding the opposite first.
For example, to solve -4 - (-2) + 5:
- Step 1: Address the subtraction. Change - (-2) to + 2. The problem becomes -4 + 2 + 5.
- Step 2: Solve from left to right. -4 + 2 = -2.
- Step 3: Complete the final operation. -2 + 5 = 3.
10. What is the difference between adding whole numbers and adding integers?
The main difference is that whole numbers are always zero or positive, while integers include positive and negative numbers. When adding whole numbers, the result always increases or stays the same. When adding integers, the result can increase or decrease depending on the signs of the numbers being added.
