Number Line

Numbers can be shown in a number line where the number zero is taken as origin. Positive numbers are usually placed on the right of origin while negative numbers are on its left, as shown in the figure below.

Math Tutorials: Number Sets, Positive and Negative Numbers and Number Lines Example

It is evident that the value of numbers increases from left to right in the number axis.

We use arrows to represent any increase or decrease of a number in the number line. For example, when the number 2 increases by 5 units, we can express this event in the number line as follows.

As a result, the new number obtained is 7 because 2 + 5 = 7. On the other hand, when the same number decreases by 8 units, we obtain

Negative numbers are very important; they allow us to express quantities that are smaller than zero. For example, if the outside temperature in a cold winter day is 5 Celsius degrees below zero, we write t = -5°C. Likewise, if a given location is below sea-level, we take its altitude as negative. For example, instead of saying "The Dead-Sea as the lowest place on Earth is 1360 ft below sea level", we simply say "The altitude of the Dead-Sea is -1360 ft."
