Hi,

I'm moving a stack installation to a new server including upgrading moodle from 3.1 to 3.3

Maxima is installed and healthcheck page looks great...

I've troubles w/ matrices display in questions.

attached are images of old and new servers. (working and not working)

any help will be appreciated...

The question is :

(text)

Let \({\bf A}\) and \({\bf B}\) be the following matrices: \[{\bf A} = @matrixa@\] 

\[{\bf B} = @matrixb@\]

Find the sum \({\bf A + B:}\)

input:ans1 validation:ans1

(variables)

matrixa:matrix([rand_with_step(-5,5,1),rand_with_step(-5,5,1)],[rand_with_step(-5,5,1),rand_with_step(-5,5,1)]);

matrixb:matrix([rand_with_step(-5,5,1),rand_with_step(-5,5,1)],[rand_with_step(-5,5,1),rand_with_step(-5,5,1)]);

correctanswer:matrixa + matrixb;

wronganswer:matrixa-matrixb;

thanks a lot,
