UMS Calculator has guaranteed accuracy of results

If you use any calculator for scientific or technical calculations, you must be confident in the reliability of results. This means that the result computed by the calculator should be as close to the true value as possible. But what if the result calculated differs from the true value more than 1000 times?! Think about the consequences of such an error when you are seeking a precise answer! You would probably agree that this calculator is not worth using. What should you do? If you believe that your present calculator gives reliable answers with precision up to n significant figures, try solving the following problem. (This expression must be entered in full, not calculated in steps – hope your calculator allows this!):

Every calculator we are aware of (including Windows Calculator) is wrong by thousands of times. No calculator gives the correct answer!

The UMS Calculator can help you!

Using various well-known and expensive mathematic software packages (such as Mathematica, Mathcad, Math Lab, etc.) to get precise results requires user expertise, which takes a long time to acquire. This substantially limits their application.

UMS Calculator is a simple and intuitive tool, so that even an inexperienced user will be able to immediately calculate the precise values of functions of any complexity, summations of series, limits, derivatives, etc. All calculations can be easily inserted into the UMS Editor and converted into MS Word format. UMS Calculator is supplied with a multi-window full screen editor; allowing for the entry of complex formulas with constants and variables in the same format as they are recorded in a paper notebook.

UMS Calculator is included in UMS Online .
