Question

Represent the following number on a number line: $ + 8$.

Answer 1

Hint: In this question we have to represent a positive number on the number line. So we will first draw a number line representing the negative and positive integers with $0$ in the centre. We know that all the negative numbers lie on the left hand side of $0$ and all the positive numbers lie on the right hand side of $0$ . After this we will find the given number on the number line and mark it.

Complete step by step answer:
Let us first understand the definition of a number line. We know that a number line is a representation of numbers on a straight line with equal distance between consecutive numbers.Here now we will draw a number line that represents consecutive numbers with unit distance from each other. We will plot a few negative numbers to the left hand side of the $0$ and a few positive numbers to the right hand side of $0$ .

We have to represent $ + 8$ on the number line. We will first look for the sign i.e. positive or negative, Since our number is positive that means that it has to be on the right hand side of $0$.We can see that $ + 8$ lies on the right hand side of zero, so we will mark it now.

Hence the yellow point on the number line represents $ + 8$.

Note: We should note that we can also perform operations like addition and subtraction on the number line. To add a number on the number line or real line we move to the right side for each addition. To subtract numbers on the number line we move to the left side for each subtraction. We should note that any number on the right hand side of another number is always greater than that number. For example, $1$ is greater than $ - 1$.We can write this symbolically as: $1 > - 1$ .
