1. To get the sum of these values attribute you can use JSON JMESPath Extractor, example query:

   sum(properties[0].values)
   

   Demo:

   

2. If you want to multiply it by 3 - it can be done using i.e. __jexl3() function:

   ${__jexl3((${sum} * 3),)}
   

   it will return floating point number like 10.0 if you need just 10 - call intValue() chain function

   ${__jexl3((${sum} * 3).intValue(),)}
