With a great technological advance, the computers had started to be faster, companies with Intel and AMD manufacturers of world-wide famous processors for its excellent products, wanted quicker processing spears, but they had not obtained to break the barrier temperature, that is, to manufacture a more powerful processor would be necessary to coller bigger, so that the same it could be cooled, if the companies adopted this measure to place to coller bigger to each more powerful processor, future the cabinet if she would become a coolant and a computer, being thus had not decided to create two nuclei for each processor, appearing the technology of processors x64 or 64 bits, that carried the double from information of what oldest, leaving of side the processors new two Microsoft Corporation also launched operational system the Seen Windows and the Windows Seven that had given support for the new version of the calculator, that in its new version passes if to call Microsoft Mathematics, launched already in varso 4,0 among others possesss support for system of 32 bits and 64 bits, visual resources that had been improved, and optimum of everything it is that the calculator total started to be gratuitous to all and any user who wants to usufruct of one of the most complete available tools of calculation for download in the Internet. 2.1.2. REQUIREMENTS FOR THE INSTALLATION The table to follow sample the hardware and system requirements that a machine needs to support all the functions of the program, and to offer to principle performance to the user: Table 01 Requisite 2.1.3. INSTALLATION The installation of software is well simple, is enough to execute the MSetup_x86 or Msetup_x64 for computers with processors with support the technology 64 bits, the installer is available in the electronic address, after download executes the program, software on average takes a time of 40 seconds to configure the installation, more approximately 25 seconds to be installed, and if it finishes with the installation of a system component Direct X that it is installed more or less in 23 seconds.
