Question

Using the number line, write the integer which is 5 more than –5.

Answer 1

Hint: A straight line usually represented horizontally on which numbers are placed after equal intervals is called a number line. A number line is extended to infinity in both directions. As we move from left to right the numbers on the number line increases while moving from right to left the number decreases.

Complete step-by-step answer:
In the case of the addition of two numbers, we move from that number to the next number as many times as the number to be added. For example, if 1 is added to any number x, we move to the right once as shown below –

-5 is represented on the left side of the zero on the number line, we have to find the integer which is 5 more than -5 so we move 5 places towards the right –

So, from the number line, we see that the integer which is 5 more than -5 is 0.
So, the correct answer is “0”.

Note: A number line can be used to represent various kinds of numbers; integers can also be represented on the number line. Centre of the number line is taken as zero, the numbers on the right side of the zero are positive and the numbers on the left side are negative. A number line makes it easier to compare numbers, mathematical operations like addition, subtraction and multiplication can also be carried out on number lines.
