over my pretty little head obviously but they were doing pythagorean triples( whatever they are) and ds1 came up with some formula about primitive Pythagorean triples and a way of ensuring the hypoteneuse and adjacent side are consecutive.
the teacher could not disprove it and recommended ds1 write to Cambridge professor to ask them to review it.
holy shit!
he is 14 yr9 and I'm damn proud! If a little ignorant
one of the best letters home EVER
teacher genuinely excited!
