Approximation Techniques

Definition

Approximation techniques are mathematical methods used to find solutions that are close to the actual values, especially when exact solutions are difficult or impossible to obtain. These methods play a crucial role in ancient arithmetic methods and algorithms, providing early mathematicians with practical ways to handle calculations and solve problems without the tools we have today. By simplifying complex problems into more manageable forms, approximation techniques enabled advancements in various mathematical concepts.
