👉 A formula is a set of rules that governs how to perform certain operations or calculations in mathematics, physics, chemistry, etc. It can be represented as a mathematical expression or equation and it must contain all necessary variables, constants, and unknown quantities.
For example:
1. A formula for calculating the volume of a sphere is: V = 4/3
π
r^3
2. A formula for finding the area of a triangle is: A = 1/2
