In the previous segment, we discussed subtraction of a positive integer from any integer using the number line. In this segment, we will learn how to subtract a negative integer with any integer.

## Subtraction of a positive integer

Subtracting a positive integer from any integer leads to a decrease in the value of an integer. Hence, we move to the left on the number line.

For example,

6 – 2 means ‘2 less than 6’. So, we move two steps to the left of 6. Hence, 6 – 2 = 4.

2 steps to the left

-8 -7 -6

-5 -4 -3 -2 –

0 1 2 3 4 5 6 7 8

6 – 2 = 4

## Subtraction of a negative integer

Subtracting a negative integer from any integer leads to an increase in the value of an integer. Hence, we move to the right on the number line.

For example,

6 – (-2) means ‘-2 less than 6’. So, we move two steps to the right of 6 on the number line.

Hence, 6 – (-2) = 8.
