In fact, Windows7 long since brought a fuel consumption calculator, not only convenient but also very fast.
Win7 's calculator has a lot of improvements, don't look at the beginning of the unprepossessing, but a little adjustment will be able to complete a lot of special calculations.
The simplest is to switch between the different computing versions, see the left side of the "View" menu, click here can be in the "Standard Edition", "Science", "programmer", "Statistical edition" four versions of the switch. For example, our work requires a large number of statistical operations every day, choose the "Statistical edition" is convenient.
The next is the "history" and "Digital grouping", as the name suggests, "history" can be calculated before the intermediate results to facilitate the next review and use, and the number of groups do not have to say more, accounting staff favorite.
As for the menu at the end, that's the special calculation we just mentioned. You can see that Win7 has refined it into "unit conversion", "Date Calculation", "Worksheet calculation" of the major categories, each category contains a number of specific calculations, you just want to "fuel consumption calculation" in it.
After entering the interface, you will find that Win7 allows the three parameters of "fuel consumption", "distance" and "used fuel" to be mutually variable, that is, we can calculate the result of another parameter by any two numbers. Take you now calculate the hundred kilometers of fuel consumption, as long as the top menu set into "fuel consumption (1/100 km)", and then the driving distance and this period of refueling volume into, click "Calculation" can be obtained specific fuel consumption. How much easier is it than your rotten pen?
