Hello,

I've been reading through RS Geo Approach and have noticed that several lessons have symbols that are missing in the Lessons book. This has a 2009 copyright date.

For ex:
Pg. 30. A=w h
Actually, in algebra, which has lots of formulas, the operator " " is not written.

I assume the missing symbol in both is "x."

Pg. 31
A= wh (large rectangle) - wh (square)
A= 21 9-6 6
A=189 - 36

The next two solutions all have the same error.

Another on pg33,
