We need a grammar update to support writing coordinates. I think it makes sense for a single parse to consist only of coordinates. Not a lot of coordinate/vector mathematics goes on a GCSE level and so allowing students to express
(2, 3) + (4, 5) = (6, 8)
is unnecessary.
Instead, a working line should accept a single, nth dimension coordinate. If students need to submit more than one co-ordinate for their final answer they can write it on a second line
