Calculators are equipments which are used by students, teachers or professionals to solve or explain mathematical calculations. These devices are specifically designed to provide solutions for any critical scientific problems. The characteristic of offering solutions related to advance mathematics make these modern calculating machines more different and unique from other kinds of calculators. These can be of various technologies that include electronic, mechanical, hardware or software. These are usually small and digital empowered with many built-in functions which are capable of handling scientific formulas used in chemistry or physics.

A Scientific calculator usually performs trigonometric functions such as sine and cosine, exponential functions such as square root, and miscellaneous mathematical functions. Few high-end models are designed with graphic and problem solving capabilities. The featured models in these calculators include trig functions and logarithms, factorials, 12 levels of parentheses, logs to base 2, bitwise logical operators, hex, octal, binary and ascii display. Many calculator brands produce models that are capable of features like statistics and probability calculations, programmability, equation solving, fractions, complex numbers, hexadecimal binary and octal calculations which comprise of basic Boolean math.

Scientific Calculator Models:
