How to apply a similar formula to many fields instead of step by step?

Question

for field “c” the «rude» script is:
(function() {
   // Get the field values, as numbers
   var v1 = +getField(“a”).value;
   var v2 = +getField(“c”).value;  
   // Perform the calculation
   var result = v1 * 100 \ v2
   // Set the value of this field to the result
   event.value = result;
But it this form it involves 20 operations...
It is possible to make a more logical and fast solution?

Dear try67:
Firstly, thanks again.
For some designers with a minimum of knowledge of scripting this seems a very complicated situation.
We need to help the customer but the investment of time (in this case) sounds excesive.
For many times you wrote detailed scripts and is a shame always asking the same.
Perhaps if now you may provide a bibliographical/internet reference for this situation with examples, perhaps we can solve.
It is like a matrix (?) and perhaps it has a classical formulae. 
Thank you for all and the point on the errata.
