# Lesson 1.5: Symbols of Comparison: Less Than, Greater Than, Less Than or Equal To, Greater Than or Equal To

## Symbols

< less than

⠈⠣

> greater than

⠈⠜

≤ less than or equal to

⠸⠈⠣

≥ greater than or equal to

⠸⠈⠜

## Explanation

One of the design features of UEB is that each print symbol has one and only one braille representation. The symbols for opening angle bracket and closing angle bracket are used in print to represent less than and greater than respectively. The same symbols are used in braille. Like the equals sign, both symbols are formed with a prefix and a root. Less than is formed with a dot four prefix in the first cell and dots one two six root in the second cell. Greater than is formed with a dot four prefix and dots three four five in the root cell.

Less than or equal to and greater than or equal to are each formed with three cells. Less than or equal to is formed with dot four five six in the first cell, dot four in the second cell, and dots one two six in the third cell. Greater than or equal to is formed with dots four five six in the first cell, dot four in the second cell, and dots three four five in the third cell.

A blank space is left before and after the sign of comparison. A space terminates numeric mode. The numeric indicator is required before a numeral that follows a sign of comparison.

### Example 1

9>5

### Example 2

7<12

⠼⠛⠀⠈⠣⠀⠼⠁⠃

### Example 3

10>8

The sign of comparison is used whenever the symbol appears in print. Print spacing should be followed.

### Example 4

Use < or >.
