How to type mathematical expressions?

[Baibhab Bose]

I don't know how to type mathematical symbols and equations and stuff. Like if I want to ask something here in physics forum, I need to type mathematical expressions like everyone here does. How can I do that? Do I need any software?

You don't need any software. Try reading this.

Also, if you find an example of an equation, you can "reply" and that will give you a copy of what they typed. You can then cut and paste this into your own post.

Thank you so much!'

The option of using plain text is also fine but maybe more difficult to read sometimes unless you translate it to something, like onto paper with pencil/pen.
