How is she able to shop a bag of groceries? I am wondering how someone can live a normal life with not knowing almost any math at all. My grandmother, born in 1910 and skipping most school because of WW1, was a housewife in a time when even not knowing to read and write was not a problem, but in 2021 this is no longer possible.
Budgeting has been a major problem for her. Her mentality has been. Buy on sale. No regard for the actual price.
If I state we shouldn’t eat out as an effort to save money, she will go to the store and spend 80-200 on ingredients for 1-2 meals.
Geometry is not second level math. I asked because I had 2 such cases in the family, but at times when it was not such a big deal, you seem to be trolling by talking about root square.
