Over the years, just about every Mac program and feature evolved, matured, andgrew. For 17 years, however, one program chugged along, essentially untouched: thesimple, four-function Calculator. As late as 2002, this Calculator still lacked memorykeys, a percentage key, or a CE (clear entry) key, let alone any advanced functions. Bythe time Mac OS X came along, it was the very last piece of original Mac OS softwarestill standing.
Mac OS X is a Unix-based operatng system, built on technology developed at NeXT between the second half of the 1980s and Apple's purchase of the company in early 1996. It received UNIX 03 certfcaton following its 10.5 version on Intel processors – Mac OS X “Leopard”. The history of macOS, Apple's current Mac operating system originally named Mac OS X until 2012 and then OS X until 2016, began with the company's project to replace its 'classic' Mac OS. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Macintosh computers since. Upgrading from OS X Snow Leopard or Lion. If you’re running Snow Leopard (10.6.8) or Lion (10.7) and your Mac supports macOS Mojave, you will need to upgrade.
That relic is finally gone. The new Calculator is far more potent than the humble fourfunctionprogram that preceded it. It can act as a scientific calculator for students andscientists, a conversion calculator for metric and U.S. measures, and even a currencycalculator for world travelers.

The little Calculator widget in the Dashboard is quicker to open, but the standalone Calculator program is far more powerful. For example:

If you have a pre-2008 laptop, you probably have an embedded numeric keypad, superimposed on the right side of the keyboard and labeled on the keys in a different-color ink. When you press the Fn key in the lower-left corner of the keyboard, typing these keys produces the numbers instead of the letters. (You can also press the NumLock key to stay in number mode, so you don’t have to keep pressing Fn.)
