Compare Integers on Number Line

Addition on the Number line Subtraction on the Number line Multiplication on the Number line Integers on Number Line Addition of Integers on Number Line
Subtraction of Integers on Number Line Compare Natural Numbers on Number Line Compare Integers on Number Line

Before you understand this concept, you are advice to read:

Integers on Number Line
Comparison of Natural Numbers on Number Line

Earlier you would have studied how to compare natural numbers.
Just to refresh your memory, you had studied that 7 is greater than 5.
We also write it as:
7 > 5

But, if you are to compare integers (-7) and (-5), do you still say:
(-7) > (-5) ..... Is this correct ?

Lets understand this concept with the help of following number line:



From the above number line, we can see that (-5) is to the right hand side of (-7).
And we have learned in case of natural numbers that number which is on the right hand side of other number; is always greater.

The same principle applies to integers also that an integer which is on the right side of other integer; is always greater.

Now, with this, you can conclude the following two concepts:

1. In case of negative integer; smaller the digit, greater is it value.
e.g. (-2), (-1) are greater than (-7), (-6)

2. Order of comparison is reversed, when same digits are converted from positive integers to negative integers and vice-versa.
e.g. 7 > 5

but if we convert them to negative integers i.e. (-7) & (-5),
the order of comparison is also reversed i.e. from '>' to '<' and we get:
(-7) < (-5)
