This is post number…

I’ve looked and looked. Maybe I found, but I couldn’t interpret the answer. Here’s what I would like to do,
very simple. I’ve got the Entry Title and the Date formatted the way I want them, but I’d really like to have the post number right up front where people can see it, rather than having to look at the url. Such as:

Entry Title Date
No. 340

I’m sure there must be a straight forward way to do this, but I’m stumped. The text + the variable for the number of the post. But do I have to venture into The Loop to put this in the right place? Because it’s dark in there. Like going down to grandma’s cellar.

Any hints?

Any help much appreciated.
