A formula is a mathematical expression that relates one quantity to one or more other quantities. It is often represented using symbols and mathematical operations.

- Area of a rectangle: A = length × width
- Area of a circle: A = πr
^{2} - Pythagorean theorem: a
^{2}+ b^{2}= c^{2} - Quadratic formula: x = (-b ± √(b
^{2}- 4ac)) / (2a)

Formulas are used to solve specific problems or calculate unknown quantities. When using a formula, it's important to substitute the given values into the formula and perform the necessary mathematical operations to find the solution.

Formulas can be manipulated to solve for a specific variable or rearranged to express a different relationship. For example, the formula for the area of a rectangle can be rearranged to solve for the width or length.

Formulas are used in various real-world applications, such as calculating areas and volumes, solving equations, and analyzing data in science and engineering.

Practice using different formulas to solve problems involving geometric shapes, equations, and real-world scenarios. This will help reinforce understanding and application of formulas.
