There's no way that's a fair comparison! Why didn't you compare the first workbook to the "Penny Jars and Plant Growth" section of SM!!!

Katharine Beals said...

Because SM doesn't have a "Penny Jars and Plant Growth" section.

Additionally:

The first workbook doesn't have graphing problems.

The two problem sets come, respectively, from the ultimate and penultimate chapters of IM and SM.

In what way is this not a fair comparison?

(Or are you being ironic, Auntie Ann?)

Yes.
