Critical Description
As reported on StackOverflow if a variable used as part of the math() step contains a reserved word such as "exp" the evaluation of the expression fails. For example
math('number1-expected_value').next()
results in
*GremlinServerError: 499: {"detailedMessage":"Unknown function or variable 'cted_value' at pos 20 in expression 'number1 - expected_value'","requestId":"01e3f9e6-3cf2-4af0-bf94-5a4979d488b4","code":"InvalidParameterException"}*
I am able to reproduce this in the Gremlin Console using TinkerPop version 3.6.0 using:{}
