1. The problem is to evaluate the expression $O \times 1$ where $O$ is a variable or symbol. 2. The multiplication property of one states that any number multiplied by 1 remains unchanged. 3. Using the formula: $$a \times 1 = a$$ where $a$ is any number or variable. 4. Applying this to our problem: $$O \times 1 = O$$ 5. Therefore, the result of $O \times 1$ is simply $O$.
