Calculator is one of the programs that Microsoft has "upgraded" to a much nicer interface (than what is available now) in Windows 7. The new Windows 7 Calculator now has 4 different modes :
- Standard Mode
- Statistics Mode
- Programmer Mode
- Scientific Mode
This default calculator goes above and beyond the brick on your desk by including unit conversions, date calculations, and a neat new set of "templates" that let you do things like figure out gas mileage, hourly wages, mortgage payments, leases, and more.
