+/- Plus/Minus sign Mathcad Prime?

+/- Plus/Minus sign Mathcad Prime?

Does Mathcad Prime include a ± plus/minus sign or symbol?

I think the answer is no. You can only use special fonts that windows can display like yours. However, it is no meaning. So you must define it to use.

Thanks @ttokoro  -  I figured it was worth adding (with slight hopes that they added the ± operator in Mathcad Prime)

In which way would you like to make use of such a sign?

 

You can create a function like

and use it that way

In real Mathcad you can also use it as infix operator

but in Prime this option (like so many others) is not available.

You can create the function in Prime but you only can use it in prefix mode with argument parenthesis

You may also define it as

but I guess this only makes sense if you can use it as infix operator.

Thanks @Werner_E  - When I get around to installing Mathcad Prime 10 I'll have a look at your example document.   But, my typical use of the plus/minus operator is, well, an operator.   I'll have to see if I can use a function instead of a variable. 

 

Why did we move to Mathcad Prime if they don't have the ± plus/minus operator?

What is your definition of the '+/- operator', what does it do according to you(r use of it)?

I use ± in math equations.   This is very common.

You did not answer the question about how you would like to use the +/- or how you would define it as an operator!

As I see it, while + and - are operators, +- isn't. Of course unless you define it, e.g. the way I did in my first answer (two inputs x,y and two outputs x-y and x+y).

So again - whats your definition and use case ?

 

I also don't understand what you mean by "using a function instead of a variable"!? Any operator can be seen as a mapping function, but sure not as a variable!

I would use ± as one normally would use ± in math (written on paper).  I haven't defined anything in Mathcad.

So I understand that you want to use Mathcad or Prime just as an equation editor and not for doing any calculations. Otherwise you would have to define what the result of applying your +- operator should be, if its not the 2x1 matrix which I had defined in my first answer.

My suggestion (using real Mathcad) was

The best we could achieve in Prime is just

It seems that Mathcad doesn't have a ± operator - so either some workaround would be needed for symbolic solves and calculation or use a different software tool.    I haven't tried your method yet - I still need to install Mathcad 10, I'm avoiding that (I have bad memories with connecting the license).   It isn't urgent that I have a working ± operator or reasonable equivalent in Mathcad Prime.  I was just curious if that ever got implemented.    Thanks for your help.
