1. The problem is to multiply 67 by 9000. 2. The formula for multiplication is: $$a \times b = c$$ where $a$ and $b$ are the numbers to multiply, and $c$ is the product. 3. Multiply the numbers: $$67 \times 9000$$ 4. Break down the multiplication: $$67 \times 9000 = 67 \times (9 \times 1000) = (67 \times 9) \times 1000$$ 5. Calculate $67 \times 9$: $$67 \times 9 = 603$$ 6. Now multiply $603 \times 1000$: $$603 \times 1000 = 603000$$ 7. Therefore, the product of 67 and 9000 is: $$\boxed{603000}$$
