Variables calculation

How do I...?

Hello !

Is there a way to make the addition of two variables ?

Without using another variable ?

Thanks

like set Variable(value1) to Variable(value1)+Variable(value2)
or change Variable value1 add Variable(value2)+Variable(value3)

#3

Yes, use Set variable var1 add Variable(var2)

Thanks guys !

I’ll give it a try.
