The Sharp EL-5120 is a scientific programmable calculator. It has about 1 KB of total RAM available to the user, and has 4 basic operational modes: Real mode: it is the basic operational mode for directly performing standard algebraic and statistical calculations, as well as evaluating user-defined functions and numerically integrating them.
Sharp EL-500W series include a range of scientific calculators made by Sharp Corporation, capable of displaying 2 lines, with multi-line playback. It is the successor to the Sharp EL-500V series . Features

The 35s stores complex numbers as single values, which can then be operated on in the standard ways. The above example of adding 12 + 34i and 56 + 78i then becomes: 1 2 i 3 4 ↵ Enter 5 6 i 7 8 +. On the 35s, the number of functions able to handle complex numbers is limited and somewhat arbitrary.
Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has a solution which is a complex number.
HP's first scientific calculator, HP-35. With this in mind, HP built the HP 9100 desktop scientific calculator. This was a full-featured calculator that included not only standard "adding machine" functions but also powerful capabilities to handle floating-point numbers, trigonometric functions, logarithms, exponentiation, and square roots.

The Sharp EL-8, also known as the ELSI-8, [1] was one of the earliest mass-produced hand-held electronic calculators [1] and the first hand-held calculator to be made by Sharp. Introduced around the start of 1971, [ note 1 ] it was based on Sharp's preceding QT-8D and QT-8B compact desktop calculators and used the same logic circuits, but it ...
