A less than sign is defined as the math symbol used to compare numbers where one value is less than the other. It is an inequality symbol used to show the comparison between two or more quantities. For example, if we want to show the comparison between 2 and 3 we will say it as 2 is less than 3 or 3 is greater than 2.

The less than symbol is '<'. It is an inequality symbol as it does not establish equality between two numbers or expressions. It only tells us that one value is smaller than the other value. For example, if x < 5 is given, it means the value of x is smaller than 5. Look at the less than sign given below.

The term 'less than' means one value is smaller than the other value. The synonyms for less than are 'lower than', 'below', 'fewer', and 'smaller than'. It is represented by the symbol "<". If we flip this symbol, we get the symbol for greater than. So, ">" is 'greater than symbol' in math.

The less than sign (<) always points towards the smaller number or expression. The wide end of the symbol faces the bigger number, making it look open towards the larger value and 'pointing' at the smaller one.
