Hello guys!
I made a question using Formulas that the required answer is in algebraic formula. The problem is (pic1), whenever student typing in the answer box, there is no display response (interpretation) shown.

Could someone help me please, what to do in order the student input box (answer) will automatically  in real time render the input into easy recognized expression such as shown in the figure (pic2).

I have tried several change to the setting but to no avail.
