Number System
In mathematics, a number system is a set of symbols used to represent values, count quantities, perform arithmetic operations, determine orders and compare amounts. There are different number systems. The Base 10 (Decimal) number system is the most commonly used, which uses ten distinct symbols 0-9 to represent values zero to nine. Different number systems are used in many fields. For example, in the field of computer science, the Base 2 (Binary) and Base 16 (Hexadecimal) number systems are commonly used. The Binary number system uses two distinct symbols 0 and 1 to represent values zero and one. The Hexadecimal number system uses sixteen distinct symbols, with the numeric symbols 0-9 to represent values zero to nine, and alphabets A, B, C, D, E and F (or a-f) to represent values ten to fifteen.

What is the Base 36 number system? The Base 36 number system uses thirty-six distinct symbols, with the numeric symbols 0-9 to represent values zero to nine, and alphabets A-Z (or a-z) to represent values ten to thirty-five.

What number system do we use for measuring time?
We use the Base 60 (Sexagesimal) number system, where one hour of time is divided into 60 minutes, and one minute is divided into 60 seconds. The time measurement of "8 hours, 28 minutes and 32 seconds" is represented by three Base 60 numbers as 8:28:32.
