It hardly feels like the greatest of priorities right now, does it? We've got a health service in absolute chaos. an economy teetering on the brink and it would be easier to list public sector workforces that aren't planning strikes than those that are. Then there's the minor matter of a conflict in Europe that could well escalate to WWIII. And he comes out with this jolly wheeze of an idea? Has he even stopped to think where exactly the extra maths teachers are going to come from?
Besides all that, whilst maths is a valuable skill, it's not for everyone and that's OK. Pupils should be encouraged to focus on things they are good at, not forced to embrace the PM's pet subject.
