In 7th grade math, half our grade was the daily quizzes which were supposed to drill in the ability to do chained calculations recited aloud rapid-fire by the teacher, but simply separated those who could keep up from those who couldn’t. I aced all written tests, failed all the quizzes, and got a C.
On the math example in the video, it’s easy to keep a running total, calculator-style, on the second run-through… but only if I ignore operator precedence. That seems to be the intent, but it feels wrong.
