lol if you want the population to not be full retard you need to teach these basic subjects, these are also a basis for physics, engineering and such...
lol if you don't wanna force people to learn math, why learn physics, chemistry biology, hell even history, cuz you don't need it for your specific profession. this way more than half important subjects are useless to you because your future job may not need it.
either way people's average IQ would stand at 40-50 without atleast basic math being taught at school.
plus, even if you really don't understand math, you don't need to learn it at a high level, just going minimum is easy as fuck, all you need in a basic functional logical brain to get an easy 100.
no math = no education = no job
