Think all desktop calculators are the same, just with different buttons? You're pretty much right. Most basically replicate the look and functions of a handheld calculator on your desktop. The built-in Windows calculator is fine for quick jobs, while some scientific and mathematical desktop calculators wouldn't look out of place hanging from an engineering student's belt. Then there's SFR Calculator Personal Edition. The best description we can come up with is a Windows calculating utility. SFR integrates a number pad, of course, since it's essential, but its built-in document feature lets you save, annotate, and … Read more

You probably change your computer every couple of years and update your phone based on Apple's release cycles. But chances are that inside your briefcase or in your desk drawer, there's a gadget that hasn't been changed for decades. It still works well, and you like it just the way it is.
The device in question is the HP 12c calculator, first launched exactly 30 years ago today, on September 1, 1981. Ever since, without much fanfare, it's been a quietly vital tool in finance, business, and academia. According to HP, the 12c is still one of only two standard calculators permitted for use during financial professional certification exams. This is because when it was released, the calculator offered more-accurate computations than the federal standard. It also features an unmatched keypad layout that provided unprecedented ease of use. The device itself is compact enough to fit in a pants pocket.… Read more

Scientific calculators are kind of like wildlife tags, clearly identifying certain individuals as nerds, who themselves view the tricorder-size devices as badges of honor and marks of distinction.

Like any modern operating system, Mac OS X includes a calculator app. It loads quickly and can be used for simple formulas, but it's not the fastest way to arrive at a mathematical truth on your Mac. Instead of opening the calculator app, likely by typing some part of "calculator" into the Spotlight search box, and then closing the calculator app when you're done, you can use Spotlight itself as a calculator.
Just type a mathematical expression into Spotlight, and it will return the answer--as the top result, right in the window. It's best for … Read more
