5. Calculation on  Command Prompt.

• The command processor CMD.EXE comes with a mini-calculator that can perform simple arithmetic on 32-bit signed integers:                                                                  
  C:\>set /a 2+2                                                                                                                                   
  4                                                                                                                                                       
  C:\>set /a 2*(9/2)                                                                                                                                 
  8                                                                                                                                                         
  C:\>set /a (2*9)/2                                                                                                                                    
  9                                                                                                                                                   C
  :\>set /a "31>>2"                                                                                                                                 
  7                                                                                                                                                    
  Note that we had to quote the shift operator since it would otherwise be misinterpreted as a "redirect stdout and append" operator.
  For more information, type set /? at the command prompt.

6. Create Nameless File and Folders.

• This trick will allow you to create files and folders without any name.Just follow the steps as given below :-

1. Select any file or folder.
2. Right click on it, select 'Rename' or simply press 'F2'.
3. Press and hold the 'Alt' key. While holding the Alt key, type numbers '0160' from the numpad.                                                                                                                                      Note :- Type the numbers '0160' from the numpad, that is, the numbers present on the right side of the keyboard.Don't type the numbers which are present on top of the character keys.
4. Press Enter and the nameless file or folder will be created.

• Reason :- The file or folder that seems nameless is actually named with a single space.

• But what if you want to create another nameless file or folder in the same directory ?For this you will have to rename the file with 2 spaces.Just follow the steps given below 

1. Select file, Press 'F2'.
2. Hold 'Alt' key and type '0160' from the numpad.
3. Release the 'Alt' key. Now without doing anything else, again hold 'Alt' key and type '0160'.
4. Press 'Enter' and you will have second nameless file in the same directory.
5. Repeat step 3 to create as many nameless files or folders in the same directory.
