A basic example is if the correct answer is "1e10", an answer of "1 e10" will submit and be marked incorrect (other spaces, like "1e 10", are considered invalid answers and give a warning when submitted, or are marked correct (eg " 1e10")). The 'interpretedStudentAnswer' appears to be the same in both cases, so I am unsure if the entry with a space represents a 'different' answer.
I can see how a student might add this space for the sake of easier reading.
