In what looked like a series of equations, Jim Davis scribbled numbers and letters across a whiteboard at Lafayette High School.
This wasn’t Algebra. Or any high school math class, for that matter.
The formulas on the board revealed strategy in the game of bridge, and the eight students in the classroom listened before launching into a few games of their own.
Davis, 73, teaches the card game to nearly 80 students across eight Williamsburg-James City County schools.
