The Sharp EL531XTWH is a fully featured scientific calculator that performs 273 advanced scientific and mathematical functions. Direct Algebraic Logic lets students enter the elements of an expression in the exact order they appear in the textbook, and the two-line dot-matrix display keeps the entry visible above the answer so an error can be caught before it propagates. Two modes, normal and statistics, cover one- and two-variable statistical work alongside general calculation, and eight temporary memory buttons hold intermediate results through a long problem. It suits students studying general maths, algebra, geometry and trigonometry, and carries over well into statistics, biology, chemistry and general science. Twin powered, in a durable gloss black finish with a protective hard case.
