1. The problem appears to be an equation: $9 \cdot 10 \cdot 298 = -1$. 2. Let's analyze the left side: multiply $9$, $10$, and $298$. 3. Calculate $9 \times 10 = 90$. 4. Then multiply $90 \times 298$. 5. Calculate $90 \times 298 = 26820$. 6. So the equation becomes $26820 = -1$. 7. This is clearly false since $26820 \neq -1$. 8. Therefore, the equation $9 \cdot 10 \cdot 298 = -1$ is not true. 9. If the problem was to verify or solve this equation, the answer is that there is no solution because the left side is positive and the right side is negative.
