Soulver is my favorite Mac calculator app, because it doesn’t act like a normal calculator. Imagine that you have a piece of paper on which you jot calculations. Then, the paper works out the results for you. Soulver is like that — you type in the sums, and it solves them. You can rework the problems, just like you could on paper, and you can save the whole sheet. And now, in v3.3, the app’s maker added a brand-new Spotlight-like QuickSoulver popup panel that lets you perform instant calculations.
If you don’t already know it, then this tip is about to blow your mind. It’s the paper roll for the Mac’s Calculator app, which has been a feature since, like, forever. You may have been using the Calculator since the very beginnings of Mac OS X, and yet you may still have never seen it.
There’s an old proverb: “The best time to plant a tree is twenty years ago. The second best time is today.” That totally applies to the Mac Calculator’s paper toll. Let’s check it out.
Doing a bit of quick adding-up in the iPhone calculator app? Or are you in the middle of a complex series of calculations better suited to a spreadsheet, but you used the Calculator anyway? A mis-hit key can spell anything from annoyance to disaster, forcing you to bang on the C key a few times to reset the the whole calculation, and start over.
But it doesn’t have to be that way. With this quick pro tip, you can easily delete just one digit at a time.
As crazy as it sounds given the wide range of use-cases Apple makes possible with the iPad, it has never shipped with a built-in calculator app. And, according to a recent post on Twitter from a user claiming to be an ex-Apple employee, we may finally have an explanation.
Shock horror: it involves Steve Jobs being a perfectionist.
As the world gets smaller and smaller thanks to the global marketplace called the internet, you may sometimes need to know exactly how much your dollar will get you in the wider world. Is that £15 widget really worth it? You’ll only know if you convert it to some form of currency that you understand better.
Your Mac has at least three ways to do this sort of calculation: with a Dashboard widget, the built-in Calculator app, and even with Spotlight. Here’s how to convert currencies into something that makes more sense, right from your handy Mac computer.
Sometimes, when you’re tapping away at a calculator, it helps to hear what you’re typing in. It’s like a second stream of information for your brain, and it helps keep things more accurate. There are a variety of talking calculators on the market, and a bunch of iOS apps that do the same thing.
Did you know, however, that you can make the calculator bundled in with OS X talk to you, too? Me neither.
We’ve talked before about all of the Braun products that have inspired Apple’s designs. Perhaps the best known is the Braun ET66 pocket calculator, first released in 1987 replacing the earlier ET22 model which inspired iOS’s own calculator app and has become a Dieter Rams design classic.
Outside of inside your iPhone, it’s hard to find a working ET66 these days, which is why it’s so great that Braun intends on re-releasing the original model later this year as an official replica. No word on price or exact availibility yet, but I know I’ll be getting one. Won’t you?
