The Power of the Charlie Face

Last night’s precalculus class was a world of fun and I believe that after the “smiling Charlie Brown face” that I will excel at math! During the factoring review, the professor drew a four curves, two upper, two lower, which coincidentally symbolized the Charlie Brown face (though she did not know if the two lower curves were either his nose or his chin!) That was the first time that I heard this version of the FOIL method!
