See http://numbas.mas.ncl.ac.uk/question/219/bills-copy-of-addition-whole-number-place-value-decomposition/ For answer to Part 1 I have a length restriction of minimum 8 characters and require also that + must be included. However if the correct answer is say 300+30+4 then if I input 300+34 then this is marked as correct even though there are only 6 characters.
You've forgotten that the marking algorithm puts spaces around + and - in the student's answer, so 300+42 goes to 300 + 42, which is 8 characters long.

300+42
300 + 42
