*whew* I barely made it!

Geezo Peezo, My Webbies and myself empathize, it is an intense challenge especially for we who are mathematically challenged (art:math like oil:water)!
We are perservering between levels 2-3 and are determined to make the grade.
What I want to find is an on-line 'game' that offers the same type of mathematical demands in order to practice, so if anyone knows of such......... please advise as to where to link!
