Windows 7 comes with a lot of new features. But, even as the new ones always sound more interesting, we cannot forget that the operating system has more to offer.

This post is about an older utility. Windows has been shipped with this program since Windows 1.

Maybe, you haven’t use it a lot, and I am sure you have been looking for an electronic calculator sometimes even with your computer on, but, why not take a close look to the new Windows 7 Calculator?

Looking for more uses for Windows 7’s new calculator?

## History

This is a really useful feature. Now, you can see what has been done before and check if the operations are correct. Press **Ctrl + H** to view the history.

In the View menu we have 2 new modes.

## Programmer

This is the kind of feature we all wanted to have 20 years ago. If you want to make some binary operations or hexadecimal math this is a good option.

## Statistics

First you should enter the numbers of your calculation using the Add button. Once you finish with this it can show the average of the values, average of the square of the values, sum of the values, sum of the square of the values, standard deviation, standard deviation of population.

## Date Calculation

Date calculation is always complex, so why not leave your computer do the math? It can calculate the difference between two dates, and also add or subtract days to a specific date.

## Unit conversion

Do you need to convert between two units? Using the new calculator, you can convert units of angle, area, energy, length, power, pressure, temperature, time, velocity, volume, weight, and mass.

## Worksheets

In the view menu, we find under the worksheets section several options.

### Mortgage

It asks for some parameters and calculates the down payment, monthly payment, purchase price, and term of the mortgage.

### Vehicle Lease

The same as with the mortgage. In this case you can calculate the lease period, value, periodic payment, and residual value.

### Fuel economy

Do you want to know how much fuel your car is using? This feature just makes the division between the numbers, but in case you need it the option is here and can also make calculation using liters and kilometers.

Who knew the new calculator has so many new features? Looking for more uses for Windows 7’s new calculator?
