The Sharp EL546XTSL is an advanced scientific calculator for students moving past introductory maths. Direct Algebraic Logic lets an expression be entered exactly as it appears in the textbook, and the two-line, 12-digit dot-matrix display shows the entry and the result together so a mistake is visible before it is committed. Its 470 functions span six modes — normal, statistics, complex, matrix, list and equation — with quadratic and cubic solvers, three-variable linear equation solving, and one- and two-variable statistics. Physical constants and metric conversions are built in. Eight temporary and four formula memory buttons keep intermediate work available. Suited to pre-algebra through calculus, trigonometry, statistics, biology, chemistry and physics. Twin powered, with a protective hard case included.
