The term "greater than" is a mathematical symbol represented by the symbol ">" and is used to compare two numbers or values. When one number is larger than another, we say that the first number is greater than the second. For example, in the expression 5 > 3, the number 5 is greater than 3. In everyday situations, "greater than" can also apply to other contexts, such as comparing sizes, ages, or quantities. For instance, if a person has 10 apples and another has 7 apples, we can say that 10 apples is greater than 7 apples. This concept helps us understand relationships between different values.
