FAQs on Examples of Addition of Integers on a Number line & Obtaining Additive Inverse Video Lecture - Mathematics & Pedagogy Paper 2 for CTET & TET Exams - CTET & State TET

1. What is addition of integers on a number line?
Ans. Addition of integers on a number line refers to the process of combining two or more integers by moving forward or backward on the number line. It involves adding the magnitudes of the integers and considering the sign rules to determine the sum.
2. How can I represent the addition of integers on a number line visually?
Ans. To represent the addition of integers on a number line visually, you can start by locating the first integer on the number line. Then, move forward or backward according to the value of the second integer. The final position on the number line will represent the sum of the two integers.
3. What is the additive inverse of an integer?
Ans. The additive inverse of an integer is the number that, when added to the original integer, results in a sum of zero. For any integer 'a', its additive inverse is represented as '-a'. In other words, the additive inverse of a positive integer is its negative counterpart, and vice versa.
4. How can I find the additive inverse of an integer?
Ans. To find the additive inverse of an integer, simply change the sign of the integer. If the integer is positive, its additive inverse will be negative, and if the integer is negative, its additive inverse will be positive. The absolute value remains the same.
5. Can you provide an example of addition of integers on a number line?
Ans. Sure! Let's consider adding -3 and 5 on a number line. Start by locating -3 on the number line, then move 5 units forward. The final position will be 2, representing the sum of -3 and 5.
