1. The problem states: Evaluate the expression $3 - 3 = 6$ and verify if it is true. 2. The expression $3 - 3$ means subtracting 3 from 3. 3. Using subtraction rules, $3 - 3 = 0$ because any number minus itself equals zero. 4. Therefore, the statement $3 - 3 = 6$ is incorrect. 5. The correct evaluation is: $$3 - 3 = 0$$ 6. So, the final answer is $0$, not $6$.
