Not knowing algebra eliminates nearly every STEM profession.
Since Algebra was not around until the 9th century AD, I must challenge that assertion.
Roman roads, bridges, aqueducts, harbors etc. are still extant. No Algebra.
Some will confuse Boolean Logic with Algebra. It’s not the same. Former computer programmer here.
And, as a former machinist as well, used Geometry & Trigonometery. Never Algebra.
I don’t mean to get into a pissing contest with anyone here, and I wish someone, anyone, would help me out here BUT
VERY few, use Algebra in their everyday lives...
And you would not want to delve into the forms of mathematical proof they relied on to make geometry work before algebra.
I will be 85 in a few weeks, and I use basic math and geometry everyday. The last time I used algebra was my soph. year in college to barely get through Algebra II in college.
My wife was in the top 5% of the RN tests she took in Illinois, Virginia and California. She used real math all day in her different roles as an RN. %’s and basic math were used all day.
Our grand daughter is also an RN and basically uses algebra and calculus to relax her brain during break time. She loves any math and was the top math student in Junior high and a top ranked private high school.
Her younger brother is a new construction project manager and uses algebra/calculus/physics all day his dad.
