Mathematics: Comparing Numbers
Comparing Numbers
It is good to know if one number is bigger, smaller or the same as another number!
We use these signs to compare numbers:
=  If two values are equal, we use the “equals” sign  example: 2+2 = 4 
<  But if one value is smaller than another, we can use a “less than” sign.  example: 3 < 5 
>  And if one value is bigger than another, we can use a “greater than” sign  example: 9 > 6 
Less Than and Greater Than
The “less than” sign and the “greater than” sign look like a “V” on its side, don’t they?
To remember which way around the “<” and “>” signs go, just remember:
 BIG > small
 small < BIG
The “small” end always points to the smaller number, like this:
Greater Than Symbol: BIG > small
Example:
10 > 5
“10 is greater than 5”
Example
10 > 5
“10 is greater than 5″
Or the other way around:
5 < 10
“5 is less than 10″
Do you see how the symbol “points at” the smaller value?
… Or Equal To …
Sometimes you know that a value is smaller, but may also be equal to!
 Example, a jug can hold up to 4 cups of water.So how much water is in it? Until you measure it, all you can say is “less than or equal to” 4 cups.

To show this, we add an extra line at the bottom of the “less than” or “greater than” symbol like this:
The “less than or equal to” sign:  ≤  
The “greater than or equal to” sign:  ≥ 
As well as the familiar equals sign (=) it is also very useful to show if something is not equal to (≠) greater than (>) or less than (<)
These are the important signs to know:
=  When two values are equal  example: 2+2 = 4 
≠  When two values are definitely not equal  example: 2+2 ≠ 9 
<  But when one value is smaller than another  example: 3 < 5 
>  And when one value is bigger than another  example: 9 > 6
