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
⠼⠒⠈⠡⠲⠀⠨⠅⠀⠼⠂⠆
6+5∙2 > 15

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
⠼⠲⠤⠦⠀⠨⠅⠀⠤⠼⠲
-5-5 = -10

-13+10 = -3
