Completely understand the relationship between fractions and percentages;
Long division;
Multiplication;
How to calculate square roots and cube roots;
Completely understand plane geometry to include the differences among squares, rectangles, circles, cubes, cylinders, parallelograms, rhombuses, radii and diameters.
Enough English to know the differences between "differences between" and "differences among."
In short, I learned everything I need to hold a job because I did my homework in grades 1 through 10.
I confess I forgot how to calculate a square root. Ditto cube root (if I ever knew)
However..... My I Phone can do it in a flash to 14 decimal places and convert the anglo value to metric in the bargin
I hated homework. I thought of it as busy work. I did it, though, without any help from anyone. There was no one to ask for help. My brother always told me that he wasn’t going to help me because I should be able to figure it out by myself.
I loved geometry, though. I loved the progression of rational thought in the theorems. I saw as a kind of brain teaser. When my daughter took geometry, however, it wasn’t the same. They didn’t learn to prove the theorems, they were just supposed to memorize them and apply them and there tests were all scantron, so there was no learning from the mistakes, either.
So, uh, what did you learn at school?
