# 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 $9$.
