\[7={\color{red}1}\times2^{2}+{\color{red}1}\times2^{1}+{\color{red}1}\times2^{0}={\color{red}111}\]

\[7={\color{red}1}\times2^{2}+{\color{red}1}\times2^{1}+{\color{red}1}\times2^{0}={\color{red}1}{\color{red}1}{\color{red}1}\]

maybe something better exists..(html+css +js (+php)) :) 

..you cannot use your own HTML+CSS+JS+PHP on 3rd party website like this forum..

You have to use what is built-in website.

This part of the forum (The Sandbox) is for testing such built-in features.

Permission to execute JS + PHP on a third party would allow deep surveillance of forum members, person identification, hacker attacks, money theft etc.

this is correct ,I also sometimes add the mechanism of +TCP,UDP protocols and all the content relevant to this.

but in spite of these details, I see many people using their own websites,though. Can we say that most of them were not sufficiently knowledgeable?

About LaTeX:

I have not used it so much and I was supposing that it would not contain good/shining colours. (i.e. not suitable for a good presentation)

setting formulas, colours , borders , etc ...this is a part of programming that might require good work.

\[ \frac{\sqrt{FE_R} \left( \sqrt[4]{FE_R} \right)^2}{\frac{E_R}{c^2}} = \left( FE_R \right)^{\frac{1}{2}+\frac{2}{4}} \frac{1}{c^2} =\]

\[  =\frac{FE_R}{\frac{E_R}{c^2}} =Fc^2 = \frac{G}{c^2}c^2 \]
