Subtract Using Number Lines
Concept
Subtraction on number line helps us to visually perform the subtraction operation on small numbers. A number line is a visual representation of numbers on a straight line that can be used to perform different arithmetic operations like addition, subtraction, multiplication, and division.
Subtraction on a number line helps to subtract smaller numbers very easily. While subtracting numbers on a number line, we need to jump (move) towards the left-hand side of a number line. We always start with the minuend and move towards the left according to the number given as the subtrahend. ‘Minuend’ is the number from which we subtract and ‘subtrahend’ is the number which is subtracted.
Rules
1. Mark the minuend on the number line.
2. Move towards the left-hand side of the number line according to the number given in the subtrahend.
Example
Subtract using the number line.
9 – 4
Solution
1. Mark the minuend on the number line.
2. Move towards the left-hand side of the number line according to the number given in the subtrahend.
9 – 4 = 5

Subtraction – to take away from a group or a number of things.
Number Line – a line on which numbers are marked at intervals, used to illustrate simple numerical operations.
Minuend – the number from which we subtract
Subtrahend – the number which is subtracted.
Difference – The final result after subtracting the subtrahend from the minuend.
