Windows has always had a calculator, but for the most
part it was a pretty cheap calculator. Windows 7 has substantially
improved the calculator, adding more functions. You can now use the
calculator in Windows 7 for everything from calculating your recent gas
mileage to statistical analysis.
To run the Calculator, choose Start→All
Programs→Accessories→Calculator. You'll probably see
the standard, basic Calculator window.
The
standard calculator,
showing its Unit Conversion option.
With the Calculator in standard mode and with the basic
configuration, you can do simple mathematical operations by entering
the values to be computed separated by the operators (+ for addition, -
for subtraction, * for multiplication, and / for division) and then
clicking the equal (=) key.
Keep in mind that you can enter
your numbers and mathematical operators into the Calculator by either
clicking the onscreen buttons or using the number keys or numeric
keypad
on your keyboard.
The Calculator has three separate modes that you can switch
to by selecting them from the View menu (or pressing the shortcut
keys shown in parentheses):
-
Scientific
(Alt+2): Adds keys for performing trigonometric calculations
— great for all the engineers out there.
-
Programmer
(Alt+3): Adds keys for performing programming calculations in
different number systems, including hexadecimal,
octal, and binary number systems, along with the usual decimal system
using different word and byte sizes (and if you don’t know
what that is, you probably don’t need this mode).
-
Statistics
(Alt+4): Adds keys for doing statistical calculations
involving linear regression.
The new Calculator also offers the following specialized
configurations (also available from the View menu) designed for more
complex calculations:
-
Unit Conversion
(Ctrl+U): Adds fields for converting all sorts of
measurements (angles, pressures, temperatures, weights, time,
velocities, mass, and so on) from one set of units to another.
-
Date Calculation
(Ctrl+E): Adds fields for performing calculations between two
dates.
-
Worksheets:
Adds fields for calculating results, such as finding the necessary down
payment or your monthly mortgage payment; the residual value of a
leased vehicle; or the fuel economy of your vehicle.
Press Alt+1 to return the Calculator
immediately to standard mode from any of the other three modes and
press Ctrl+F4 to return to the basic configuration from any of the
other available configurations.
