When the learning curve on math material is shallow, then it is easier to learn it to understand it well? But it is harder to memorize a few key formulas quickly?
People actually prefer to just memorize a few formulas than to try to learn a subject at a gradual pace?
This is especially true for students?
Math materials are demand driven not supply driven?
We assume that the nature of math materials reflects the suppliers and their limitations?
Is it really the demand side that wants easy to memorize materials that don’t require them to understand them very well?
