Editor's Pick: High school and college STEM students often need to work out fractions, square roots, and trig functions for homework. This two-line display lets you see both the expression you entered and the result at the same time, so you don't have to keep pressing buttons to check whether you made a mistake earlier. With dual solar and battery power, you don't have to worry about the battery running out in the exam room. It's allowed in the SAT, ACT, and AP exam rooms.
