So, here's your survey back.
I removed all not relevant questions.
As you see, all calculations are in ONE question of type "equation".
But in my opinion you do not want to display the results to the respondents, so they can change them, do you?
Therefore you should hide the questions Q33 and Q34.
Or you only use four equations, where you do not assign values, but only calculate them.
