My mom was in college when the shift happened and she said that the “New Math” was pretty much the same thing as the “Old Math.” She and I can understand each other’s longhand arithmetic, but when she says an equation out loud she uses baffling prepositions “and” “into” “from” “by” that I can comprehend, but I have to spend several seconds converting those words into “plus” “minus” “divided by” “times”
