Google’s calculator tries to understand the problem you are attempting to solve without requiring you to use special syntax. However, it may be helpful to know the most direct way to pose a question to get the best results. Listed below are a few suggestions for the most common type of expressions.
Most operators come between the two numbers they combine, such as the plus sign in the expression 1+1.
Operator Function Example
+ addition 3+44
- subtraction 13-5
* multiplication 7*8
/ division 12/3
^ exponentiation (raise to a power of) 8^2
% modulo (finds the remainder after division) 8%7
choose X choose Y determines the number of ways of choosing a set of Y elements from a set of X elements 18 choose 4
the root of calculates the nth root of a number 5th root of 32
% of X % of Y computes X percent of Y 20% of 150
Some operators work on only one number and should come before that number. In these cases, it often helps to put the number in parentheses.
Operator Function Example
sqrt square root sqrt(9)
sin, cos, etc. trigonometric functions (numbers are assumed to be radians) sin(pi/3)
tan(45 degrees)
ln logarithm base e ln(17)
log logarithm base 10 log(1,000)
A few operators come after the number.
Operator Function Example
! factorial 5!

How To Restrict Login Hours Allowed
To restrict a users logon hours , use the net user command. These commands are used from the Command Prompt. (Start - RUN - and type cmd)
Below are some examples:
1 - net user parthi /time:M-F,08:00-17:00
2 - net user basha /time:M-F,8am-5pm
3 - net user Indu /time:M,4am-5pm;T,1pm-3pm;W-F,8:00-17:00
4 - net user monsoor /time:all (this one means this user can always log on)
Note:You can only restrict when a user can log on to the system. On a stand alone computer, there is no way to force a user to log off when their hours expire, without a third party script or software.
Below are some examples:
1 - net user parthi /time:M-F,08:00-17:00
2 - net user basha /time:M-F,8am-5pm
3 - net user Indu /time:M,4am-5pm;T,1pm-3pm;W-F,8:00-17:00

Create One-Click Shutdown and Reboot Shortcuts:
First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC.
But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this:
shutdown -r -t 01 -c "Rebooting your PC"
Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use.
I use this technique to create two shutdown shortcuts on my desktop—one for turning off my PC, and one for rebooting. Here are the ones I use:
shutdown -s -t 03 -c "Bye Bye m8!"
shutdown -r -t 03 -c "Ill be back m8 ;)!"
Switch
What it does
-s
Shuts down the PC.
-l
Logs off the current user.
-t nn
Indicates the duration of delay, in seconds, before performing the action.
-c "messagetext"
Displays a message in the System Shutdown window. A maximum of 127 characters can be used. The message must be enclosed in quotation marks.
-f
Forces any running applications to shut down.
-r
Reboots the PC.

How To Find Serial Numbers On Google
This is a little trick that i usually use to find CD keys with google.
if your looking for a serial number for Nero (for example) goto google.com and type Nero 94FBR and it'll bring it up,this works great in google
HOW DOES THIS WORK?
Quite simple really. 94FBR is part of a Office 2000 Pro cd key that is widely distributed as it bypasses the activation requirements of Office 2K Pro. By searching for the product name and 94fbr, you guarantee two things.
1)The pages that are returned are pages dealing specifically with the product you're looking a serial for.
2)Because 94FBR is part of a serial number, and only part of a serial number, you guarantee that any page being returned is a serial number list page.
I hope this trick help you finding your CD keys easily
Enjoy :)

Google Tips & Tricks
==================================================
Utilizing search engines
==================================================
So much information is on the web, its mind boggling. Thankfully we have search engines to sift through them and categorize them for us. Unfortunately, there is still so much info that even with these search engines, its often a painstakingly slow process to find exactly what you're looking for.
Lets get right into it.
I use google.com as my primary search engine because it presently tops the charts as far as the sites that it indexes which means more pertinent info per search.
--------------------------------------------------------------------------------
method 1 : Goto - www.google.com
put this string in google search:
"parent directory " /appz/ -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
"parent directory " DVDRip -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
"parent directory "Xvid -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
"parent directory " Gamez -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
"parent directory " MP3 -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
"parent directory " Name of Singer or album -xxx -html -htm -php -shtml -opendivx -md5 -md5sums
Notice that i am only changing the word after the parent directory, change it to what you want and you will get a lot of stuff.
method 2 : Goto - www.google.com
put this string in google search:
?intitle:index.of? mp3
You only need add the name of the song/artist/singer.
Example: ?intitle:index.of? mp3 jackson
