A number system, also known as a numeral system, is a way of representing numbers using symbols or digits. The most commonly used number system is the decimal system, which uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each digit’s position in a number represents a power of 10. For example, in the number 356, the digit 6 represents the ones place, the digit 5 represents the tens place (10^1), and the digit 3 represents the hundreds place (10^2). | School of Mathematics, Nigeria
