Step-by-step explanation: The numbers on a number line are placed sequentially at equal distances along its length. It can be extended infinitely in any direction and is usually represented horizontally. The numbers on a number line increase as one moves from left to right and decrease on moving from right to left.
Different Types of Numbers on a Number Line
A number line can be used to represent any type of numbers, like fractions, decimals, integers, etc.
Number Lines as Mathematical Tools
To compare numbers
Writing numbers on it makes comparing numbers easier. Numbers on the left are smaller than the numbers on the right of it.
To add/subtract numbers
A number line can also be used to carry out addition and subtraction. We move right to add, move left to subtract. Let’s have a look.
Steps to add/subtract on a number line:
Locate the first number on the number line.
To add: move as many steps as the second number to the right.
To subtract: move as many steps as the second number to the right.
The number you land on is the answer.
To multiply/divide numbers
A number line can also be used to carry out multiplication and division. We skip count on a it to show jumps of equal size.
