What is the base 10 math theory?

Base 10, also known as the decimal system, is a numeral system that uses ten symbols (0-9) to represent numbers. It operates on a place value system where the position of each digit determines its value, based on powers of ten. For example, in the number 345, the 3 represents 300 (3 × 10²), the 4 represents 40 (4 × 10¹), and the 5 represents 5 (5 × 10⁰). This system is widely used in everyday life due to its simplicity and effectiveness in representing quantities.
