When you first take an algebra class, you should learn how to perform basic addition and subtraction equations first. This allows you to understand the basics of algebra. After you master this, you should move on to multiplication and division. To solve for multiplication equations, you need to apply the opposite operation to each side of the equation. For example, if one side of the equation says to multiply by three, you need to divide both sides by three to simplify and solve it.
