Balanced ternary is a ternary numeral system (i.e. base 3 with three digits) that uses a balanced signed-digit representation of the integers in which the digits have the values −1, 0, and 1. This stands in contrast to the standard (unbalanced) ternary system, in which digits have values 0, 1 and 2.
A ternary / ˈ t ɜːr n ər i / numeral system (also called base 3 or trinary [1]) has three as its base. Analogous to a bit , a ternary digit is a trit ( tri nary dig it ). One trit is equivalent to log 2 3 (about 1.58496) bits of information .
This template is designed principally to expand one parameter- for example an American K-12 grade into grade, ages, and English year groups. It can work from grades, year groups and ages. Usage
The base −r expansion of a is then given by the string d n d n−1...d 1 d 0. Negative-base systems may thus be compared to signed-digit representations, such as balanced ternary, where the radix is positive but the digits are taken from a partially negative range. (In the table below the digit of value −1 is written as the single character T.)
In some places, .25 or .3 instead of .33 is added for a plus grade and subtracted for a minus grade. Other institutions maintain a mid-grade and award .5 for the grade. For example, an AB would receive a 3.5-grade point and a BC would receive a 2.5-grade point.

The base case b = 0 follows immediately from the identity element property (0 is an additive identity), which has been proved above: a + 0 = a = 0 + a. Next we will prove the base case b = 1, that 1 commutes with everything, i.e. for all natural numbers a, we have a + 1 = 1 + a.
