[StackOverflow|https://stackoverflow.com/questions/74121856/gremlin-reserved-word-exp]
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
{code:java}
math('number1-expected_value').next(){code}
results in
{code:java}
