FAQs on Addition and Subtraction of Integers - 2

Question 1

1. What is addition of integers?

Accepted Answer

Ans. Addition of integers refers to combining two or more integers to find their total or sum. It is a mathematical operation where positive and negative numbers are added together according to specific rules. For example, adding a positive integer and a negative integer results in subtraction.

Question 2

2. What is subtraction of integers?

Accepted Answer

Ans. Subtraction of integers is the process of finding the difference between two integers. It involves taking away one integer from another to determine the result. The rules of subtraction with integers involve changing the sign of the number being subtracted and then adding it to the other number.

Question 3

3. How do you add integers with the same sign?

Accepted Answer

Ans. When adding integers with the same sign, you simply add their absolute values and keep the same sign. For example, when adding two positive integers, you add the numbers together and keep the positive sign. Similarly, when adding two negative integers, you add the numbers together and keep the negative sign.

Question 4

4. What happens when you add a positive integer and a negative integer?

Accepted Answer

Ans. When adding a positive integer and a negative integer, you subtract the absolute value of the negative integer from the absolute value of the positive integer. The result takes the sign of the larger absolute value. If the absolute values are equal, the sum will be zero.

Question 5

5. Can you give an example of subtracting integers?

Accepted Answer

Ans. Certainly! Let's consider the subtraction of -8 from 3. To subtract a negative integer, you can change it to its positive equivalent and then perform addition. So, -8 becomes +8. Now, you can simply add 3 and 8, which gives us 11. Therefore, subtracting -8 from 3 results in 11.
