API
There's a single query parameter expression that expects an arithmetic expression. (, ), +, -, *, and / are supported.
Order of operations is respected.
There must be a space between each operator and number. If the expression is valid, the result is returned as a string with a status code 200.
If the expression is invalid, an error message is returned with a 400 status code.
From the command line:
curl -G --data-urlencode "expression= ( 2 + 2 ) * -10" localhost:8080
curl -G --data-urlencode "expression= 2 + 2 * -10" localhost:8080
