ELI5: Why does the math they teach in school keep changing and getting harder?
gpt
One could argue that 3+5=8 hasn't changed in, forever.

The pressure is to teach **more math** in the same amount of time.  That means that more intensive techniques need to be used, and students must **work harder**.  It's not the math that's different, it's how much math you need that's changed since your parents were in school.
