Guys:

Just to clear up a potential point of confusion:
a) '(9/2)*6-3'
==> (9/2)*6-3 = (4.5)*6-3 = 24 is a correct answer for the combination (2,3,6,9)
b) '(9*5+4)/2'
==> (9*5+4)/2 = (45+4)/2 = (49)/2 = 24.5 is an invalid answer for the combination (2,4,5,9)

You must use 'real world' math, not the incorrect integer math module build into KiXtart.

I have updated the rules to reflect this issue.

I have also removed the EXECUTE statement that checks for correct answers since it will fail if the '/' is used and the operation results in fractions. This was an oversight in my coding since I forgot about the messed-up integer math in KiXtart.
