:D

exten => 11099,1,SUM(RV,1,20)
exten => 11099,2,NOOP(${RV})
exten => 11099,3,MULTIPLY(RV,10,2)
exten => 11099,4,NOOP(${RV})
exten => 11099,5,DIVIDE(RV,10,2)
exten => 11099,6,NOOP(${RV})
exten => 11099,7,SUBTRACT(RV,10,2)
exten => 11099,8,NOOP(${RV})
exten => 11099,9,MODULUS(RV,2,10)
exten => 11099,10,NOOP(${RV})
exten => 11099,11,DIVIDE(RV,10,0)
exten => 11099,12,NOOP(${RV})
exten => 11099,13,SUBTRACT(RV,10,200)
exten => 11099,14,NOOP(${RV})
exten => 11099,15,DIVIDE(RV,1,20)
exten => 11099,16,NOOP(${RV})
exten => 11099,17,LT(RV,1,20)
exten => 11099,18,NOOP(${RV})
exten => 11099,19,GTE(RV,1,20)
exten => 11099,20,NOOP(${RV})
exten => 11099,21,GT(RV,101,20)
exten => 11099,22,NOOP(${RV})
exten => 11099,23,EQ(RV,1,20)
exten => 11099,24,NOOP(${RV})
exten => 11099,25,LTE(RV,20,20)
exten => 11099,26,NOOP(${RV})


results in:

   -- Executing Sum("Zap/2-1", "RV|1|20") in new stack

   -- Executing GT("Zap/2-1", "RV|101|20") in new stack
   -- Executing NoOp("Zap/2-1", "TRUE") in new stack
   -- Executing EQ("Zap/2-1", "RV|1|20") in new stack
   -- Executing NoOp("Zap/2-1", "FALSE") in new stack
   -- Executing LTE("Zap/2-1", "RV|20|20") in new stack
   -- Executing NoOp("Zap/2-1", "TRUE") in new stack

My $0.02 (USD)

We shouldn't use seperate applicaiton registrations for each function.  IMHO, each function should be able to be used in a string, for example:

exten => 11099,1,Math(RV=1+20)
exten => 11099,2,NoOp(${RV})
exten => 11099,3,Math(RV=10*20)
exten => 11099,4,NoOp(${RV})

and so on..  You get the Idea I think.

Added, but merged into one application called "Math" with multiple operations.
