Aa an engineer and citizen I have become aware of two major problems in america. Well two vig ones that i see cause us to have dumb people one is that we dont use the metric units as the standard and the other being bad communication skills.
I learned mix numbers so long ago as a kid. While they are useful for recipes and maybe measuring in inches. That seems like an anerican based problem.
When you go onto higher maths and a number next to a fraction means to multiply is by the numerator a part of me thinks back to mixed numbers. Little changes like this does alot of damage in the long run imo. If you talk to a mathmetician they goke that they dont do subtraction. Because adding negative numbers in effect does the same thing and teaches you to use the number line intuitively.
I think this in part creqtes confusion and is part of the reason America is known by itself as inferior engineering.
Also it's always been on my mind but only recently did i really investigate long division and it's use of remainders. For awhile as a kid i might have found the skill useful but in school my answers had to be exact meaning including all the decimal's. I've just been thinking about all the unnecessary things thst would make msth more clear .
I dont really rhink the msth it'self is the problem but in america people dont like to talk to each other and arent honest. So importsnt details are often skipped over.
Even miles per hour is abbreviated to mph and im looking at my car dashboard right now and it says km/hour. So living in idk london a child that sees km/hr intuivelty knows that its an hour devided into how many kilometers you will trsvel inthst time. That has to make math and science much easier for them.
