In mathematics, an operation is a function which takes one or more inputs (called operands) and produces an output. Some of the most common operations include addition, subtraction, multiplication and division, all of which take two inputs and produce an output. These are called binary operations, and are often used when solving math problems. Other types of operations are called unary operations, which take only one input and produce an output.
There are more operations than these, including raising numbers to exponents, taking the root and applying the logarithm.
Below is a list of the most used operations.
