Calculator

Modern electronic calculators are small (often pocket-sized), digital, and usually inexpensive devices to perform the basic operations of arithmetic.
In addition, there are scientific calculators and Graphing calculators which focus on operations more complex than those specific to arithmetic.

Types of calculators

Basic Calculators -
Designed to perform basic mathematical operations like +, -, *, /, %, and Square root.

Scientific Calculators -
Designed to calculate problems in science (especially physics), engineering, and mathematics.

Features of a modern scientific calculator -

Scientific notation for calculating large numbers
floating point arithmetic
logarithmic functions, using both base 10 and base e
trigonometry functions (some including hyperbolic trigonometry)
exponents and roots beyond the square root
quick access to constants such as pi and e

In addition, high-end scientific calculators will include:

hexadecimal, binary, and octal calculations, including basic Boolean math
complex numbers
fractions
statistics and probability calculations
equation solving

Graphing calculator -
Calculators that are capable of plotting graphs, solving simultaneous equations, and performing numerous other tasks with variables.
Most popular graphing calculators are also programmable, allowing the user to create customized programs.

Features of graphing calculators -

Graphing
Calculus
Complex Numbers
Economics & Finance
Linear Algebra
Probability
Sequences
Applications
