The Win8 system adds a lot of new features, and everyone is upgrading to the WIN8 system for these new features. But this for the users just contact WIN8 system, there are many functions do not know how to use. Take calculator function, Calculator's function is very powerful, this everybody knows. Not only can you calculate multiple steps at once, but you can also perform a variety of functions, or you can perform different numerical calculations. So

Windows comes with a calculator, which is exactly the same as a scientific calculator. If it is a complex computing formula, it is easy to be processed by complex Geography AlgorithmThen it gets dizzy. Speq mathematics is a lightweight calculator that can be computed using a long string of mathematical formulas. This method makes it easier to repeat and calcula

Problem description: James, who opened the hotel in the Software Park, was very depressed recently. He often encountered errors during account verification, and his computing results were always biased. After knowing this, Mr. Wang planned to solve this problem for James. After investigation, he found that the problem occurred on the calculator. The calculation method of the current calculator is mostly: i
