I'm wondering how to input a therefore sign in Mathematica?

For example, I want to input / output something like:

∴ a == 2 + 1 // TraditionalForm
∴ a = 3

However, I get a syntax error. I'm guessing this is because the \[Therefore] is Therefore[x, y] that needs two arguments.

Doing Therefore[None, TraditionalForm[a == 2 + 1]] just seems to output None ∴ a == 3

I don't want to just use a text cell for this purpose, since I would like this to be dynamic.

Any help? Thanks!

  • $\begingroup$ You need it to have "2+1" and not 3? $\endgroup$ – Jason B. Apr 18 '16 at 13:08
  • $\begingroup$ No, I do want the 2+1 to be evaluated to 3, if that's what you mean? $\endgroup$ – Michael Yoo Apr 18 '16 at 13:09

    $\begingroup$ I was going to suggest Therefore["", TraditionalForm[a == 2 + 1]] or Row[{"\[Therefore] ", Dynamic[a], " = ", 2, "+", 1}], either may suit your needs $\endgroup$ – Jason B. Apr 18 '16 at 13:10
  • $\begingroup$ @JasonB The Therefore["", ...] seems to work, although it is a little messy but I can't find any other way of doing it. Thanks for the help! $\endgroup$ – Michael Yoo Apr 28 '16 at 9:51
