Maths?

Are we Brits genetically bad at maths, poorly taught or what? It seems so many of us ND and NT really struggle with it and have done for years, so much so that it almost seems to be a point of national pride that we're collectively so bad at it.

All I know is that I'm terrible at it and couldn't pass a GCSE grade 3, even with special tutoring, it meant I failed my access course, luckily it didn't stop me going to uni because I didn't need maths for history. What makes it even worse is I seem unable to use a calculator either, I can put the same numbers in 3 times and get 3 different answers.
