 Yes, we do. So I learned one new thing. So we were talking about the calculator on iOS, where you get a different calculator if you rotate your device. Right. Right. Yeah, that's right. A couple of episodes ago. Yeah, exactly. Yeah. And then someone commented in the comments section for that episode, and then we went on a brief tangent talking about RPN, which is Reverse Polish Notation, which is a different way of creating equations for your calculator to interpret. But yeah, somebody said iOS doesn't have this, and I'm like, you know what, let me do a search here, and guess what, Dave? The macOS calculator has an RPN mode. Seriously? Yeah. I didn't know that. Yeah, well, you know, I found the article. So what you do is, on macOS, you bring up the calculator. Hold on. Yeah, so there's the calculator. Go to the View menu, and then there's an RPN mode selection, which you can check or uncheck. Neat, huh? Look at that. Fascinating. For example, like one thing you could do, so the way RPN works is you put something on the stack, then you end, so like, for example, you can say five, enter, four, enter, and then times. That's how RPN works. Right. Instead of saying five times four, you say five, and then four, and then times. Right. You're reversing the notation. Yeah, exactly. Yeah. Yeah. Interesting. That's, and it's kind of a computer thing. You know, it's like a stack-based concept, I guess you could call it. Anyways. Command R in the calculator, and I can attest to the fact that this works in Big Sur and Monterey, at the very least, because I'm still on Big Sur here in the studio.
