On the Macintosh: Calculator
Using its View menu, you can switch the Windows calculator between its basic four-function and scientific modes. The Mac’s Calculator desk accessory (Apple menu → Calculator) can’t do anything more than basic four-function math. At the high end is the Mac’s Graphing Calculator (Apple menu → Graphing Calculator), which can solve and graph complex equations.
For a reasonable calculator in between those two extremes, you’ll have to turn to a third party calculator, such as the freeware Calculator II, available from the web site http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/sci/calc/calculator-ii-15.hqx.
On the Macintosh: CD Drives
CD drives for accessing CD-ROMs and audio CDs are standard equipment on Macs and PCs today, with the notable exception of laptop computers that lack room for a CD drive. For the most part, using CDs on a Macintosh is similar to using them on Windows, with a few caveats.
Inserting and removing CDs. You insert a CD into a Macintosh just as you do on a PC—press the eject button on the drive, insert the CD, and press the button again (or push the tray gently) to close the tray. (On newer models, such as the late-1999 iMac, there’s no tray; you insert the CD directly into the slot.) CDs on the Macintosh appear on the Desktop like any other disk; once a disc’s icon appears, you use it exactly like any other disk (except that you can’t write data to a CD, of course).
