Estimate the product of `183xx153` by rounding off the first number upwards and the second downwards.

Answer

To estimate the product of 183 and 153 by rounding the first number upwards and the second number downwards, we can follow these steps:

### Step-by-Step Solution:

1. **Round 183 Upwards:**
- The nearest hundred to 183 is 200. Since we are rounding upwards, we take the next hundred.
- Therefore, 183 rounded upwards is **200**.

2. **Round 153 Downwards:**
- The nearest hundred to 153 is also 100. Since we are rounding downwards, we do not change the number.
- Therefore, 153 rounded downwards is **100**.

3. **Multiply the Rounded Numbers:**
- Now, we multiply the rounded numbers:
\[ 200 \times 100 \]
- Performing the multiplication:
\[ 200 \times 100 = 20000 \]

4. **Final Estimated Product:**
- The estimated product of 183 and 153 is **20000**.

### Summary:
The estimated product of 183 and 153, after rounding 183 upwards to 200 and 153 downwards to 100, is **20000**.
