Today I`m going to explain why an inequality with 'equal to' needs a closed dot rather than an open one. There needs to be a closed dot because there is no need to be a  open because there isn`t any at least or any more than. for example there is a equation like 5b> 25 I would first try to minus out the 5 by doing the opposite of opperations after that I would know that b>5. thats basicly is what you have to do I hope

I thing that you should have put more to the title than just math
