# Definition of Equation

An **equation** is a mathematical expression that tells us that two things are equal.

Equations always include the equals sign, "\( = \)"

Here are some examples of equations:

- \(2 \times 3 = 7 - 1\). This says that \(2 \times 3\) and \(7 - 1\) are equal to each other. They are! They are both equal to \(6\).
- \(3x + 3 = 9\) is another equation. It says that \(3x + 3\) has to be the same as \(9\).
