Input box show variable name instead of its value
f(x) = 3x
a = 3
b = 4
I insert a button with the Click-script: "f(x) = a + b"
When I click on the button, "f(x) = 3 + 4" is shown in the Algebra window.
If I then insert an input box and choose to relate it to the function f, "a + b" is shown in the input box. If I then set it to "Symbolic", "a + b" is still shown in the input box, but in LaTex style.
This is a very nice feature when using an input box in relation to algebra. I would therefore very much like to preserve this option.
But when it comes to use an input box to show a calculation with numbers, it's a bit annoying that it show variable names instead.
Therefore I'll suggest that the value of the used variables are shown as standard, and the name of the used variables only is shown when "Symbolic" is checked.
But of cause there may also be a third usage where the teacher would like to show an expression in an input box that both contain numbers and the name of some variables. For example: "3a + 7b". In that case you would probably need to think of a third option to make this possible. Or the teacher would need to create a text-string that shows this instead of getting it shown in a input box. But of cause, when creating a lot of input boxes, it would be a bit easier and faster just to get the correct answer to be shown in each input box.
