What Does Ternary Mean?
Ternary is a term for base-three arithmetic. A ternary number system can contain a total of three digits, such as 0, 1 and 2 (as opposed to something like binary code, which is often expressed through ones and zeros). Base-three number systems have many different applications, particularly in computer science and programming.
Techopedia Explains Ternary
A good way of understanding base-three math is by comparing it to the common decimal (or denary) system, which consists of a total of ten digits (0 through 9). When ascending the decimal system in numerical order and the final digit (9) is surpassed, digits are added to the left, which in turn ascend in numerical order as required.
