Casio 2-Line 249 Function Scientific Calculator

Calculator includes a full slate of functions including stats, fractions, trigonometry, combination and factorial. Two-line 249-function scientific calculator provides one independent memory and six constant memories. Solar plus feature protects memory no matter what the lighting conditions. When you are done, a hard case protects the screen.
