Use Command Prompt as Calculator

No, i'm not saying about typing "calc". Just wanna tell u that thr's a CUI calculator available in command prompt. It can perform simple arithmetic on 32-bit signed integers: Examples: 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. "set" command can help setting various others parameters in your system.
