On a number when the circle is filled in does it mean Greater than/greater than or equal to or Less than/less than or equal too? Same with a circle that's not filled in.

Is the sign greater than/greater than or equal to, less than/or less than or equal to. That's what it depends on..

On a number line? When it's filled in it just means inclusive, whether it's greater than or less then depends on which direction the line is going, if there's a line going right from 3 with a filled in circle at 3, it means greater than or equal to 3, it the circle isn't filled in it just means greater than 3

phi · Answer

The idea is that if you say, for example,
x>2  then x cannot be 2
we put an open (unfilled circle) at 2.  The "empty" circle is supposed to remind us that 2 is not included in the answer... because x>2 means x is not 2.
