The modern mobile phone solves many problems in addition to calls. The organizer and camera, radio and Internet browser and more. I want to dwell more on such a de minimis, at first glance, the functions of your phone as a calculator. Function, in my opinion, quite unfairly overlooked side. Thus, any modern phone is equipped with a set of basic applications, which includes a calculator. However, trying to take advantage of this free addition, you surprise yourself, come with a number of annoying inconvenience. Most calculators supplied base smartphones do not hold either a competition with their hardware (desktop) brethren. This is inconvenient in handing, often ugly application capable to perform only basic mathematical operations such as addition, subtraction, multiplication and division. You will tell me that this is quite enough. Of course! You are quite right, for the solving of ordinary, daily tasks that are more than enough (and you Hardly used it more than couple times since the purchase of your phone) and for the rest there are appropriate devices, used to work with numbers. But let me draw your attention to one little fact: We do not carry a calculator in the right pocket of our pants, wherever we go, never! (Or almost never) But our mobile phone is always with us. And whatever happens, we can always use it - is only necessary to run the program. Try it - you will like it. NiceCalc- is Verysoft LLC product family.
