Sharp EL-506TSBBW Engineering/Scientific Calculator, Black

The Sharp EL-506TSBBW is an advanced engineering and scientific calculator designed for students studying higher-level math and science, including pre-algebra, algebra, geometry, precalculus, calculus, trigonometry, statistics, biology, chemistry, and physics. It features a large 12-digit, 2-line LCD display with Direct Algebraic Logic (D.A.L.), which allows calculations to be displayed as they are written on paper. This model offers 470 functions across 6 modes: Normal, Stat, Equation, Complex Number, Matrix, and List. Key functions include quadratic and cubic equation solvers, substitute algebra with simulation calculations, matrix calculations, complex number calculations, N-Base calculations (HEX, BIN, DEC, OCT, PEN), list calculations, differential and integral functions, and formula memories. It has eight temporary memories, four formula memories, one independent memory, and one last answer memory. The calculator also supports equation editing and playback, 1, 2, and 3 variable statistics, normal and stat modes, and six regression types. Additional functions include logarithms, reciprocals, powers, roots, factorials, normal probability, trigonometric, and hyperbolic trigonometric functions. The device features a glossy black finish with white accents, a home key that clears all data and settings, and acrylic display protection. It includes a 3D light reflecting protective hard case and operates on hybrid power (solar and battery).
