Ideal for engineers, surveyors, college students, scientists and medical
professionals.

Accuracy, functionality, dependability. Scientific projects require these vital
attributes for success. The pocket-sized HP 33s scientific programmable
calculator delivers them - and more - with features that include 31KB user
memory, your choice of RPN and algebraic data-entry modes, a powerful two-line
display, and the timesaving HP Solve application. Permitted for use on SAT I, SAT
II Math IC/IIC, ACT, PSAT/NMSQT, AP Chemistry/Physics, PLAN, EXPLORE?.
