Along the way, Christopher reviews the 200+ new features in Mountain Lion, which gives even experienced Mac users a valuable head start.
At one time, if you wanted to let your geek flag fly, you packed a very expensive scientific calculator. Well now, if you have a Mac, there's no need because Mountain Lion equips your Mac with a Calculator application that does more that meets the eye. Let's launch it and here's what appears to be a very simple Calculator. On it, you can do basic math, so you can click buttons, 89 * 63 = 5607. And I can then clear it.
So, perform basic calculations here, using the mouse if you like, or your trackpad, or if you have a keyboard that has a number pad on it, you can do your calculations there. Now, if you don't have a number pad on your keyboard, there's another way to do this. Hold down the Function key, which is marked Fn, and type in numbers using the Alternate keys. In this case, J, K, and L equal 1, 2, and 3. U, I, and O equals 4, 5, and 6. And then 7, 8, 9 are -- that's 7, 8, 9.
The question mark equals plus, the semicolon is a minus, P equals multiply, and 0 equals divide. Or you can just use the number keys at the top of your keyboard. This is a perfectly fine little calculator, but let's suppose you want to get a little bit nerdier, no problem. Go to View and choose Scientific. Now, we're getting serious. Now, if you don't happen to be a card caring scientist, and not all of us are, you can go to View and choose instead Programmer.
Look at all those zeros. So, you can create all the ones and zeros you like, and before you know it, you're a professional programmer. Now, as it turns out, I'm neither one of these things, so I pretty much stick with the basic calculator. Now, one of the calculator's less well-known charms is its ability to perform conversions. So, you enter the number you want to convert and then you choose a conversion you want to perform. So let's say, 100, Convert, and we'll say Length. So, I want to convert from feet to kilometers.
So, 100 feet equals 0.03048 kilometers. As you can see, in the Convert menu, there are lots of conversions you can perform, Area, Currency, Energy or Work, Length, Power, Pressure, Speed, Temperature, Time, Volume, And Weights and Masses. One of the most helpful ones is the currency converter. So let's say, I have a 100 US Dollars and I want to find what that's going to get me in Indian Rupees.
Click on Convert and that's 3947.00012207 Rupees. And when you choose Currency, it will tell you when it was last updated. Now, if this date seems out of date to you, you can click on Update and it will choose the most recent conversions, and these are all coming through Yahoo!. So, if you find yourself in a country not your own and you want to find out what your money buys you, and you have a laptop with you, try using the Convert feature.
If you're connected to the internet, you should be able to get the current rate. Calculator has a couple of other tricks. The first is that it can speak button presses to you, which helps you when you're not looking at the screen. So go to Speech and then Speak Button Pressed. "Speech enabled. Clear, 78 - 21 =" but it doesn't tell you what it actually equals. So, what do you have to do instead, is actually look at your computer and say, "Oh, it equals 57." So, it tells you the calculation, but it won't tell you the result unless you turn on Speak Result from the Speech menu.
Let's try that again, "Clear, 26 + 31 = 57." Now, let's turn off Speech because I don't really need Alex telling me everything I'm doing with the Calculator. The other thing you can do is Show Paper Tape. So, if you're performing a lot of calculations, this is a good way to keep track to double check your work. And if you don't want the rest of the world knowing what you've been calculating, you can click on Clear to get rid of those results.
Also, anything that appears in the paper tape can be copied and pasted into another application. And that's Calculator, another small, yet valuable tool bundled with Mountain Lion.
