> When I’m on Zoom with a client, I can’t say “Excuse me a second. Something you said gave me an idea, and I’d like to pull out my calculator app.” You can't? Have you thought about investing in a separate device for doing calculations? A good scientific calculator is tens of dollars, and would probably blow your calculator app out of the water in terms of usability (mmm, those tactile buttons). They're even solar powered so you never need to worry about charging. Just because phones can replace handheld electronics, doesn't mean they must. Don't get me wrong, mental math is great, and in my work, I do a lot of off-the-cuff estimation with orders of magnitude and limiting behavior. But a calculator is way more precise, and can handle way more complexity than my poor little head. I tend to use a repl in my favorite language. But it sounds like the author is using their phone for zoom and can't switch windows for some reason.
