It's a very useful tool, and if you ever used it, you might have noticed the interesting functions it has. The Windows 10 calculator provides you with a lot more functions than its previous versions. Now you don't need any other apps to convert currencies, units of volume, weight, area and other things, and the calculator will do all that work for you. To open it, click on the Start button and find the Calculator app if you search by letter C. On your desktop, you can simultaneously have several calculators opened in Windows with adjustable size. When you start it for the first time, the calculator opens in a normal mode. To choose another one, click on the Menu button fashioned like three lines, the hamburger button, and open an additional panel where you can choose the mode you need from the list. Standard Scientific Programmer, Dead Calculation and Converter Depending on the difficulty of your calculations, choose the corresponding mode. In the Standard mode for basic math tasks, Scientific for complicated calculations, Programmer for working with binary codes, Dead Calculation to work with dates, and Converter to convert units of measurement. For example, if you need to work with complicated calculations, use the Scientific mode, as the calculator will work sequentially in the Standard mode. As you can see, with the same conditions, we get different answers, because in the Standard mode, the calculator doesn't observe the first rule of math. When you switch between the modes, current calculations will be cleared, but the operating system saves them in history and memory. In such modes as Standard Scientific and Programmer, you can save numbers into memory, and history keeps all formulas you have used since the app was started. To save a new number into memory, click the MS button. To retrieve it from memory, click MR. To show the list of numbers saved to memory, click on M, if you need to adjust the window size to show the folder list, for example. To add or subtract a number saved in the memory, click on the buttons M plus or M minus accordingly. To clear the memory, click on MC. In the Dead Calculation mode, you can quickly find out how many days that there are in a selected period between the two dates. As well as in other programs, you can use key shortcuts in the calculator to make your work easier. For example, by pressing the Add key, you can calculate the square root of the number you have entered. By pressing Ctrl L, you can clear the app's memory. Now let's have a closer look at Converter. Here you can quickly convert one currency into another. All you have to do is to enter the amount of the currency you need to convert into another one. For example, you have dollars into rubbles, euros, produce pounds, and so on. Below, you can see the relevant exchange rate for the current date and time. You can always click on Update Rates if the date differs from the current one. You can also learn how many gallons are in 5 liters. As you can see, it's a bit more than 1.09 gallons. If you increase the volume, you can see how it corresponds with standard baths, pools, etc. You can also work with weight and mass. For example, you can see how many kilos there are in 100 pounds. You can convert temperature, for example, from Fahrenheit to Celsius, and see that 1 degree Celsius is almost 34 degrees Fahrenheit. It's easy to convert speed. For example, from kilometers per hour into miles per hour, as you can see 100 miles per hour is the same as 160 kilometers per hour, and in the same way you can quickly change the values to feet, centimeters per second, knots, and so on. You can also find out how many megabytes make up one gigabyte, or have a look at all the possible units to measure data. You can also use other converter parts. For example, if you are looking for furniture online, find a good model on the website, but the dimensions are given in feet only. You can easily convert them into centimeters, millimeters, or another unit which you are using. As you can see, there are many other units for converting length, mass and weight, energy, area, power, pressure, angle, and so on. When you work with a computer and you need to convert one unit of measurement into another, you can always do it very quickly by using the calculator in the standard mode. If you didn't find the app on your computer, don't worry, you can install it easily. First of all, try to find it by typing its name in the search field, and if it doesn't work, go to Microsoft Store. You can find it in the Start menu. And type Windows Calculator in the search field. Or choose another one from the list that you like better and then click on Install. As a result, installation will stop immediately, the calculator will appear in the Start menu, and you'll be able to run it from there easily. If you already have the app on your PC, but it can't start, try the following trick. Go to Settings, System, Apps and Features. Select Calculator from the list, click on Advanced Options, and then Reset. Then try StartNet again.
