1. The problem is to understand the value of the number 1. 2. The number 1 is a fundamental integer in mathematics representing a single unit or entity. 3. It is the multiplicative identity, meaning for any number $a$, $a \times 1 = a$. 4. It is also the first positive integer and the basis for counting. 5. There is no further calculation needed as 1 is already a simplified value. Final answer: 1
