Due to student concern about calculator (some students use calculators and cell phones that can store formulas), today's exam is voided. We'll have midterm this Thursday. At the midterm, you are allowed to bring a BASIC calculator along with two pens/pencils and an eraser. The calculator must be BASIC only. If you don't bring a basic calculator, you'll have to do hand calculation. Wrong calculation costs half point on each problem.
Please be prepared.
Today's midterm, Version A, along with solutions, will be posted on Blackboard this afternoon. Please use it as a sample. The midterm on Thursday will be similar.
