I think it would be great if answers did not have to exclusively be integers from 0 to 999 when writing solutions. I think this is fine for math problems, but when it comes to physics problems it can sometimes be difficult to get the answer to fit within these constraints as the answers can be either astronomically large or very small. To make sure that the answer is standardized it could be written to three significant figures. A range of acceptable answers could also possibly be created so that it will accept for example an answer within 0.5 of the actual value to take into account rounding errors.
On a side note, the math isn't displaying correctly in some of the posts on my news feed but then once I click on the problem it displays correctly.
