The great thing is this follows natural speaking cadence! It feels completely natural to say it the right way but it just sounds wrong to say "high d low minus low d high", since in English we typically end sentences with a downward inflection (in the voice, not in the curve). Thanks so much for this!

I wish I the clip continued for the next two examples. I'm taking applied calculus now after being out of the classroom for several years. Your videos are a real help. Thank you
