Less than sign “<”
Greater than sign “>”
Less than or equal to sign “≤”
Greater than or equal to sign “≥”
Unlike most mathematical signs, these signs do not depend on the dots 56 as a prefix.
The less than sign in braille consists of two cells, the first cell is a prefix containing the two dots 45 followed by the next cell with the dots 26.
The greater than sign also consists of two cells, the dots 45 as a prefix, followed by the other cell with the dots 35.
While the less than or equal to and greater than or equal to signs each consists of three cells. The less than or equal to sign contains the dots 456 followed by 45, and then, the dots 26, i.e., adding the dots 456 before the less than sign. The greater than or equal to sign consists of the dots 456, then, 45 and 35, i.e., adding the dots 456 before the greater than sign.
You must leave a space before and after the comparison sign, but if the printing or conversion to braille is done from normal writing that does not contain spaces, the braille translator/ coder will put the signs without a space in line with normal writing.
A space terminates the number mode, so you must type the number sign just before the number that follows the comparison sign.
7 > 3
6 < 10
In the new Arabic Braille, it is now possible to use two signs that are less than and greater than in the normal text content without causing any conflict with the characters as was the case in the past.
Use the sign > or the sign <
$1 > 5 Yen.
