Dave has hit upon the solution to the calculator debate -change the nature
of the questions we ask our students to solve. If we continue to ask the
same kind of questions post calculator as pre calculator, then reservations
regarding calculator useage are appropriate. Instead we need to take
advantage of the technology to challenge our students to think about the
meaning behind the process.

"Have them solve -2x = 4; -2x < 4; -2x < -4; x*y > 0. Show
them concrete reasons for why they should know. "Take the calculators out of
their hands" via good problems."

"So, ask them to discuss the following sentence: "The product of the
reciprocals of a and b equals the reciprocal of the product.""
