How do you find the average value of a number?

How do you find the average value of a number? Seriously, is that even a question? I mean, it's so basic, right? But then again, I remember struggling with this in, like, seventh grade. It took me FOREVER to get it.

Finding the average? It's ridiculously simple, once you get it. You just, you know, grab all the numbers – like, say, my monthly coffee expenses: $50, $65, $40, $72, $55. I always get a little kick out of adding them up. Watching that total climb, it's weirdly satisfying. It's like, "Yeah, I spent ALL that on coffee. Oops." Then, the big reveal – the moment of truth! You divide that sum, that coffee-fueled mountain of cash, by how many numbers you started with – five, in this case. Boom! Average. It's like magic, isn't it? You get this one number that somehow represents... all of them. It feels really clever, even if it is kinda basic math. In my case, I got an average of $56.40 a month on coffee. Worth it? Debatable.
