MathOdes is a new product being advertized, but it is not the same as Math ODEs.
According to the ads, MathOdes are new study aides for "Etching Math in Memory" using music, poetry, and illustrations. An example:
The radius has a measure.
It's from center to perimeter.
The radius twice over
Completes the diameter.
To measure the circumference,
Travel the circle around once.
These compoenents are linked by
The brilliant mystery of pi.
The price....about $20 for 12 more of these "gems"! My question: Why would anyone buy (or want) these...
