In arithmetic, the inequality shows the major role. In math it has many signs like less than sign, greater than sign, less than or equal to sign, greater than or equal to sign .In this list of symbols What symbol is greater than sign is “> “. This what symbol is greater than sign specifies that the which is left hand side of the greater then sign is greater than the right side constant or variable.
Symbols - What symbol is greater than sign:
> `=>` This symbol is the specification of greater than sign.
> = `=>` This symbol is the specification of greater than or equal to sign.
>> `=>` This symbol is the specification of much greater than sign.
Rules - What is the greater then sign:
When multiply the inequality term which has the greater than sign by negative sign then the negative sign becomes positive and the positive sign becomes negative.
When divide the inequality term which has the greater than sign by negative sign then the negative sign becomes positive and the positive sign becomes negative.
Find the value of the inequality 2x+144> 8.
Sol:
Given,2x+144> 8.
Now add -144 on both sides.
2x +144 > 8.
-144 > -144
----------------------
2x > -136
Now divide by 2 on both sides so, x>-68

Draw a number line for the inequality -y+80 < 40.
Sol:
Given, -y+80 < 40.
Now add -80 on both sides
-y+80 < 40
-80 <-80
---------------
-y < -40
Now multiply the above inequality -y < -40 by negative sign.
- (-y < -40) is y > 40.
The > sign in number line start with open dot according to the inequality.
The diagram is the number line for the inequality y > 40. In this the open dot is at 4 and the arrow is towards the right.
