hi, I’ve got a question  
If I want to add or substract number variables, how can I name them to indicate they are numbers and how can I do basic math with them?

If I try adding common variables like  
\_root.answer = \_root.var1+\_root.var2;  
and if var 1 is = 1  
and var 2 is = 2  
The answer is 12 not 3

so… ? help!🔗
