# Unit 2 Signs of Operation and Comparison

# Signs of Operation

In Nemeth Code, the numeric indicator is placed before the first digit of a numeral, its affect applies to the entire number (or symbol-sequence), and it is terminated by the next empty space. There is no space between a number and a sign of operation, and the numeric indicator is not repeated after the sign of operation.

Plus (+) | ⠬ |

Minus (-) | ⠤ |

Multiplication dot (∙) | ⠡ |

Multiplication (x) | ⠈⠡ |

Division; Divide-by (÷) | ⠨⠌ |

* Notice that the multiplication cross and the divide by symbols are two-cell symbols.

# Examples:

3+3+3+3

⠼⠒⠬⠒⠬⠒⠬⠒

12-7

⠼⠂⠆⠤⠶

* Notice that the minus sign looks like the hyphen symbol. Just as in print, it is context that determines which symbol is being used.

# Signs of Comparison

The following signs of comparison are 2-cell symbols. All signs of comparison require a space before and after the symbol.

Equals (=) | ⠨⠅ |

Less than (<) | ⠐⠅ |

Greater than (>) | ⠨⠂ |

# Examples:

3x4 = 12

# Negative Numbers

A negative number is formed by placing a minus sign in front of a number. The negative sign is placed in front of the numeric indicator rather than between the indicator and the numeral.

# Examples:

4-8 = -4
