The main difference between an equation and a function is the fact that an equation usually deals with a single input, whereas, a function can have numerous inputs. In mathematics, an equation is used to denote the equality between two expressions.
A term is either a number by itself, which is called a constant, a variable by itself or a number multiplied by a variable. The number thatâs with a variable is called a coefficient. An expression differs from an equation because an expression is a group of terms without an equal sign. Identifying the terms of an expression is the first step to simplifying the expression. After youâve identified an expressionâs terms, you can perform the necessary operations on the expression.
