How to create subscript or superscript effects on blogger.com / blogspot posts

I just got an email from a friend, who asked about ^{superscript texts}, then I would like to share to the free7 blogger readers, here. As we know that, for WordPress users or another blog platforms, this is not a problem but other things if we using blogger.com / blogspot

Create a _subscript or ^superscript effects for blogspot users, the way simple enough by adding <sub> or <sup> code code ,

When you write an article select HTML mode, and then insert the hmtl code like the following into the word / phrase that is intended:

superscript code: _subscript
superscript code: ^superscript

Examples :

text_{subscript example}
text^{superscript example}

The results will be :

text _{subscript example}
text ^{superscript example}
