SHARP EL-531THBWH Scientific Calculator (White)

The SHARP EL-531THBWH is a pocket-sized scientific calculator for algebraic and scientific mathematics. Its two-line LCD display shows both the entry expression and the result simultaneously. Equations are entered using Direct Algebraic Logic (D.A.L.), mirroring the sequence used in textbooks. This model is suitable for trigonometry, logarithms, and general algebra, with a 10-digit display sufficient for standard classroom and technical work.

The calculator weighs 115 g and measures 161 mm by 80 mm by 15 mm. It is powered by a single AAA battery. The fixed, non-tilting LCD remains visible at all times, and the standard keyboard layout is designed for familiar operation. At 15 mm thick, the device fits easily into storage compartments or laptop sleeves.
