Again, you’re probably better off with a scientific calculator. For example, the trigonometry section has a degrees to radians converter, but you can’t convert from radians to degrees. I would have found this far more useful if I could have entered the result and have it reverse solve for an input. It is thus impossible to enter minus signs or decimal points!įurthermore, when entering numbers with which to solve a formula, you can only enter the inputs. When you tap on an input field, a full screen keyboard is launched (not a split screen keyboard) which is permanently set to the numerical keyboard. While testing the Quadratic solver I came across a serious limitation of the input system.

Other pages, such as the quadratic formula, make more sense, because performing such calculations with an ordinary calculator can be quite unwieldy. Was it necessary to include basic arithmetic?! (And not Algebra as stated in the screen shot!) More to the point though – why include something that is a basic function of a calculator?! Like every other page, the arithmetical pages have input fields for you to enter numbers along with a solve button. I cannot understand why anyone, young or old, would need a reminder of how to write an arithmetical expression of two numbers.

I had to do a double-take at the last section – basic arithmetic. The sections are further subdivided as follows Algebra – Exponents, Radicals, and the Quadratic Formula Geometry – Area, Perimeter, and Volume Trigonometry – Degree to Radian conversion, Trigonometric Functions, and Pythagoras’ theorem Basic Math – Addition, Subtraction, Multiplication, and Division. Each of its sections are clearly set out, and divided into Algebra, Geometry, Trigonometry, and Basic Math – Ahem, it’s “maths” or arithmetic in this case!

DAX is used in several Microsoft Products such as Microsoft Power BI, Microsoft Analysis Services and Microsoft Power Pivot for Excel. The DAX language was created specifically for the handling of data models, through the use of formulas and expressions.
