a closed dot means included
like x < 5 means less than (open)
x </= 5 means less than or equal to (closed)

Please help with the following:
What is an open dot, and what is a closed dot?
Also, when are they used in inequalities?
I am not really sure about what they are. The lesson has not taught me anything about open dots and closed dots. I have also looked them up, but I got confused. Please help, and it will be greatly appreciated. :)

Oh, now I get it!
Less than(<) and greater than(>) are open, while less than or equal to(≤) and greater than or equal to(≥) are closed.
Thank you, Damon! Your help is again, greatly appreciated. :)
