All-in-one scientific graphing tool
The CATIGA CS-121 combines scientific and graphing functions in a single unit. It plots equations, solves complex problems, and shows formulas together with their graphs. The 3 inch LCD display makes visualisation clear for algebra, calculus, and exam preparation. Students and professionals can handle advanced math without switching devices.
Anti-drop body with protective case
A durable plastic shell resists everyday impacts for long-term classroom or field use. The compact frame measures 2.4 in by 3.96 in by 1.3 in and weighs .191 kilograms, so it slips into a pocket or bag easily. A supplied case shields the screen and keys during transport. Battery power keeps it ready wherever you work.
360-plus functions replace basic calculators
Over 360 built-in functions cover fractions, complex numbers, statistics, linear regression, standard deviation, and variable solving. Angle, calculation, and display modes adapt to geometry, trigonometry, and advanced coursework. The jump is worth it when a simple scientific model no longer handles graphing or regression tasks.
