The base 10 number system, also known as the decimal system, is a number system that uses ten digits (0-9) to represent numerical values. It is the most commonly used number system worldwide. In this system, each digit's value in a number is determined by its position or place value within the number. The rightmost digit represents ones, the next digit represents tens, the next digit represents hundreds, and so on. The value of a number is obtained by multiplying the digit in each position by powers of 10 and adding them together. For example, the number 487 in base 10 represents 4 hundreds, 8 tens, and 7 ones, resulting in a total value of 487.
