## FAQs on Addition and Subtraction of Integers - 1 Video Lecture - Mathematics (Maths) Class 6

 1. What are integers and how are they different from whole numbers?
Ans. Integers are a set of numbers that include positive numbers, negative numbers, and zero. Whole numbers, on the other hand, include only positive numbers and zero, but not negative numbers. In other words, integers are a superset of whole numbers.
 2. How do we perform addition of integers?
Ans. To add integers, we follow the rules of adding positive and negative numbers. If both numbers have the same sign, we add their absolute values and keep the common sign. If the signs are different, we subtract the smaller absolute value from the larger one and keep the sign of the number with the larger absolute value.
 3. Can you explain the concept of subtracting integers?
Ans. When subtracting integers, we can think of it as adding the opposite. For example, to subtract 5 from 10, we can add -5 to 10. This is because subtracting a positive number is equivalent to adding its negative. So, we change the subtraction operation to addition and change the sign of the number being subtracted.
 4. How can we represent the addition and subtraction of integers on a number line?
Ans. Adding a positive integer means moving to the right on the number line, while adding a negative integer means moving to the left. Subtracting a positive integer means moving to the left, and subtracting a negative integer means moving to the right. By representing the integers on a number line, we can visually understand the addition and subtraction operations.
 5. Can you provide an example of adding and subtracting integers?
Ans. Sure! Let's consider the addition example: (-3) + (-5). Since both numbers have the same sign, we add their absolute values (3 + 5 = 8) and keep the negative sign. So, (-3) + (-5) = -8. For subtraction, let's consider the example: 7 - (-2). We change the subtraction to addition and change the sign of the number being subtracted. So, 7 - (-2) is equivalent to 7 + 2, which equals 9.
