I believe “common core” math is to blame. I have no idea how a child who is taught common core math can transition to algebra, geometry, trigonometry or calculus without a struggle. I do hold hope that some children have been retaught the old/correct way because of quarantine and most parents were educated the way I was - long division, etc the old school way without a calculator.
Then again I’m a math nerd without kids so what do I know? I mean like besides how to solve for X. 😂
