Equations are made up of two expressions on either side of an equals sign, like. x + 2 = 1. To solve an equation, you need to find the values of the missing numbers. 'I think of a number, add four, and the answer is seven.'.

A function is a set of mathematical operations performed on one or more inputs (variables) that results in an output. For now, functions will take one or more real numbers as an input, and return a numerical output. In more advanced classes you'll learn about far more complex functions!

more ... An equation says that two things are equal. It will have an equals sign = like this: 7 + 2 = 10 − 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1) So an equation is like a statement this equals that. Here is another equation:

A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable.

Equations are found everywhere in mathematics. Students of middle school are introduced by the equations in algebra. An algebraic equation is a combination of one or more terms separated with equal symbol =. The terms are the expressions or monomials made up of constants and variables.

$$ Y = X + 1 $$. In this case, X in the input value, and Y is the output (this is a common convention). By putting any number in for X, we calculate a corresponding output Y by simply adding one. The set of possible input values is known as the domain, while the set of possible outputs is known as the range.

Related Terms. A mathematical statement used to evaluate a value. An equation can use any combination of mathematical operations, including addition, subtraction, division, or multiplication. An equation can be already established due to the properties of numbers (2 + 2 = 4), or can be filled solely with variables which can be replaced with numerical values to get a resulting value.

It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line.

In mathematics, an equation is a statement of an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. Variables are also called unknowns and the values of the unknowns which satisfy the equality are called solutions of the equation. There are two kinds of equations: identity equations and conditional equations.
