Thank you, I really appreciate your suggestion. What are the tools you are using?

I'm not really using any such tools(I didn't need them yet.). For exponents I use libre office writer(an open source version of word), but that is useless for anything else.

I think latex would be the best choice.

Thank you for the quick response. Still, I believe that there should be some way to write complex expressions using Markdown. This documentation says something similar to that.

Yes it seems to work in some better version of markdown, but sadly not in the one used here on steemit.

Yes, you are correct. Finally, I was able to manage my problem with the help of this site. With the help of that site and markdown syntaxes, I was able to publish this blog post.

Another suggestion: Encapsule your equations with "`":
a² + b² = c² → a²+b²=c²
That way the reader can better differentiate between equation and text.

In case you don't plan to stay dependent on your website, here is how I manage those special characters:
I just put some of the useful symbols(like ∇(alt gr+shift+2) or ħ(alt gr+h) or some greek letters) on my keyboard.
And I don't know how far this is implemented on other OS's, but on Linux you can type super-/subscripts by typing ^ or ˇ once and then the symbol/number. Sadly this only works for numbers and ⁽⁾⁺⁻₍₎₊₋ . Trying to use it on letters yieds things like î and ǐ.

This is great ... I will try it on my next blog. I am also using Linux. How did you add symbols to your keyboard? Thank you
