Show Conditions - 3 Or Conditions
I'm having some difficulty with some complex Show Conditions.
I have some text that must show UNLESS checkbox a or checkbox b or checkbox c are selected.
If I input the following Show Condition on the text and press enter:
(Finda ∨ Findb ∨ Findc) ≠ 1
Geogebra changes the condition to:
Finda ∨ Findb ∨ Findc ≠ 1
which is fine - everything works!
However, if I close the file and reopen it, Geogebra change the conditions again to:
Finda ∨ Findb ∨ (Findc ≠ 1)
which doesn't work.
How do I make the brackets stay in the code? Any suggestions would be much appreciated!
