**Integers**

â€¢ The collection of all natural numbers, 0 and negatives of natural numbers are called integers.

**Representation of integers on a number line**

â€¢ All the positive integers lie to the right of 0 and the negative integers to the left of 0 on the number line.

â€¢ In order to mark -5 on the number line, we move 5 points to the left of zero.

â€¢ In order to mark +5 on the number line, we move 5 points to the right of zero.

**Ordering of Numbers**

â€¢ On the number line, the number occurring on the right is greater than that on the left and the number on the left is smaller than that on the right.Â

â€¢ 2> 1, as 2 is to the right of 1.

â€¢ 0 >-2, as O is to the right of -2.

â€¢ -5>-8, as-5 is to the right of -8.

**Addition and Subtraction of Integers**

â€¢ To add two negative integers, we add the corresponding positive integers and retain the negative sign with the sum. For example: 6 + (-5) = -(6 + 5) = -11

â€¢ To add a positive integer and a negative integer, we ignore the signs and subtract integer with smaller numerical value from the integer with larger numerical value and take the sign of the larger one (a)Â

â€¢ Two integers whose sum is zero are called additive inverse of each other.

â€¢ To subtract an integer from a given integer, we add the additive inverse of the integer to the given integer.

**Addition of Integers on a Number Line**

Let us add 3 and 5 on number line.

On the number line, we first move 3 steps to the right from 0 reaching 3, then we move 5 steps to the right of 3 and reach 8. Thus, we get 3 + 5 = 8.

**Subtraction of Integers on a Number Line**

â€¢ Subtract -4 from -5.

â€“5 â€“ (â€“4) is same asÂ â€“5 + (4), as the additive inverse of â€“4 is 4.Â We move 4 steps to the right on the number line starting from â€“5.
