# Alphabet of ternary symmetrical number system

Symbol | `-` |
`0` |
`+` |
---|---|---|---|

Numerical interpretation | -1 | 0 | 1 |

Logical interpretation | False | Uncertainty | Truth |

Alphabet naturally represents the symmetry of the system, is an international and unique (the symbols `-`

, `+`

is not found in the scripts of notation).

Convenient at hand calculations. When recording the linear expressions of symmetric ternary alphabet, it is recommended that the number of bracket.

For a concise record of symmetric ternary codes used alphabet of symmetric nonary system, with symbols: W, X, Y, Z, 0, 1, 2, 3, 4. There is the option with the Russian alphabet letters: Ж, Х, У, Ц, 0, 1, 2, 3, 4.

Conformity with symmetrical ternary system

Nonary code | W | X | Y | Z | 0 | 1 | 2 | 3 | 4 |
---|---|---|---|---|---|---|---|---|---|

Trinary code | `--` |
`-0` |
`-+` |
`0-` |
`00` |
`0+` |
`+-` |
`+0` |
`++` |

Practical application:

- Implementation of arithmetic operations:

`(+0-) * (-) + (++0) = (+0)`

- System Status:

`R = +0-+0-`

In the imaging system used 14-segment indicators, which are equally suitable for display a symmetric ternary and symmetric nonary alphabets.
