Our take on the Casio FX-260 Solar II FX260SLRS Scientific Calculator

The Casio FX-260 Solar II is a compact scientific calculator with a 10-character single-line display, solar power backed by a battery, and a pink body. It covers the basics students and test-takers need: fractions, powers, roots, logarithms, trigonometry, and constants. It is smaller and simpler than Casio's multi-line models like the FX-991, with no graphing, no equation solver, and no textbook display. It suits GED and basic math and science students who want a light, dependable calculator that runs anywhere.
