The decimal system, also known as the base-10 system, is a way of counting and representing numbers using ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

It forms the foundation for mathematics and is essential for various fields, including science, engineering, and finance. Understanding the decimal system helps
