Formula Question Issue: Substitution of Formula

1 Requirements

The substitution of the formula isn't implemented in the correct way. With the current state the question author has to take care of additional brackets around the variables, so negative values are inserted in the correct way.
 
a = -2
x = a^2
 
  • With the current state x is calculated to -4
  • The desired state should calculate x to +4
So it is required to bracket the replacements implicitly on all formula substitutions involved to the calculation process.
 
A corresponding bug was reported in Mantis: 0012881: optes: Formelfrage: Richtige Antwort wird falsch ausgewertet
