I think it is just a face.
The less than symbol looks like this: < This is where A < B ; A is less than B
The term is just "unequal" and the symbol is an equal sign with a slash through it.
it is a greater than sign
A square root sign.
The sign used to compare quantities and measurements is the inequality symbol, which includes greater than (>), less than (<), greater than or equal to (≥), and less than or equal to (≤).
The symbol for Less Than is < You read from left to right, so you read the smaller end of the symbol first. It's smaller than (or less than) the big end. An the symbol for Greater Than is > You read the larger end of the symbol first.
An inequality sign which means > more than and < less than
The less than sign < is a mathematical symbol used to indicate that one quantity is smaller than another. It is commonly used in mathematical inequalities and can be read as "is less than."

The less than sign is represented by the symbol "<". It indicates that the value on the left side is smaller than the value on the right side. For example, in the expression "3 < 5," it shows that 3 is less than 5.
It means that is is less than or equal to that number.
If a is not less than b then a is greater than or equal to b. The symbol for "greater than or equal to " is > with a bar under it -- a combination of the equal sign (=) and the greater than sign (>). In many computer languages you can use >= with no space between for this relation.
