When and How can I use mixed conditionals?

[yañez]

hi there!
well, I am a little confused with the mixed conditional tense.
I can not recognize when I have to use it.
is there anyone who could help me, please?

Here's one the most common, mixing the 3rd and the 2nd:
Past action + present result
The past action starts us off with the third conditional, but the present result requires the second:
If you hadn't asked the question, I wouldn't be answering it now.
(past action- you did ask the question) (present result I am answering it)
