Show Conditions - 3 Or Conditions

Mathimation shared this question 2 years ago

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!

Thanks!

use instead of <boolean> ≠ 1 the syntax !<boolean>

try:

! (a || b || c)

is the same as:

¬(a ∨ b ∨ c)

.

PS:

I think the changing from (Finda ∨ Findb ∨ Findc) ≠ 1 to Finda ∨ Findb ∨ Findc ≠ 1

is a small bug
