SHARP EL-W531THWH Scientific Calculator, Black, Grey

The SHARP EL-W531THWH is a scientific calculator designed for secondary and introductory university mathematics and science. It includes 422 built-in functions covering algebra, geometry, trigonometry, and statistics. A 4-line LCD dot matrix screen allows users to view multiple calculation steps simultaneously, rendering expressions clearly to assist with complex problems. It is suitable for subjects such as biology, chemistry, and general science.

The calculator is powered by a single AAA battery and uses Direct Algebraic Logic (D.A.L.) to process equations in their standard notation. To preserve battery life, the device includes an automatic shut-off feature that activates during periods of inactivity. It features a black and grey casing and does not include a protective hard cover. The display is fixed to ensure stability during use.
