I'd write the above expression as the following:
\sigma_I^2 = a^2 s^2 + (1-a)^2 S^2 + 2a(1-a) \sigma
The only thing you need to know to understand it conceptually is `_ -> move next character down`, `^ -> move next character up`.
- dash2 4y agoRight, sure. This is indeed copy-pasted from LyX, which is a saviour. Manually written, TeX can be better. But as soon as anything gets complicated, you're gonna be stuck again. The problem is not understanding something conceptually. It's intuiting it. I want my brain to be working on the maths. I don't want to use valuable brain cycles understanding the notation!
