How to write absolute value on mathway calculator

Are you sure you want to delete this answer? Yes Sorry, something has gone wrong. This will make it easier for you to backtrack it and see what you did wrong; if you made error in your math - if your proof for it, doesn't check and equal 8 While doing number 6 and 7:

You really asked two questions here, but nevertheless: Yes, Accessibility is the keyword here. Not as in "physically impaired" but as in "learned behaviour".

Some people will just want to use curly or box braces, because that's how they're rolling on paper and you want the barrier between real life application and virtual application to be as low as possible.

Users should be able to use interaction patterns they already know anything else is going to be frustratingso supporting those braces is giving them more convenience and isn't going to hurt anyone who wants to use parentheses exclusively. On question 2 Should I optimize my program for a Programmer's approach or a Mathematician's approach?

You probably know matching brace highlighting from many IDEs and Editors, where two matching braces are highlighted if your cursor is on one of them. Another approach is colour-coding, used in Excel as pointed out by stereoactivo.

Both these approaches are applicable and ease readability for both the Programmers and the Mathematicians writing style. This is where your virtual application can top the one in real life, which is always nice.

Other than that, what do you really mean by optimisation? What were your ideas on optimising for one of the two? That is certainly correct, but you care mostly about the user, not the programmer. And let's be honest, mismatching braces aren't a though thing to implement.

If we're talking about a physical calculator, you should of course consider building cost but I assume your question was meant to consider applications only.

Also, that is exactly what these additional braces are used for in the first place: If you write mismatched braces, you certainly got something twisted in your mind. Giving the user a hint upon that is certainly going to improve their experience. DR; In general, allowing users to adapt known patterns is something to be desired in every application and known to be the key factor of intuitiveness.

Therefore, supporting both writing styles, including checking for matching braces, seems to be the best solution.Nov 26,  · Is there a calculator easy to use that can solve algebra like mathway?

I have a final coming up, I suck at math, I need to know if there's is an calculator out there that isn't confusing to use but can solve most of any algebra just like algebrator or the mathway programs.
