Drake's calculation of the sum of 234 and 75 as 984 is incorrect. Let's break down the correct addition:
\[
234 + 75 = 309
\]
To find the error in Drake's calculation, we can first verify the correct addition step by step:
1. **Align the numbers for addition**:
```
234
+ 75
```
2. **Add the units place**:
- \(4 + 5 = 9\)
3. **Add the tens place**:
- \(3 + 7 = 10\) (write down 0 and carry over 1)
4. **Add the hundreds place**:
- \(2 + 1 (carry) = 3\)
So, the complete addition gives us \(309\).
The error in Drake's calculation could have come from either misreading the numbers or misperforming the addition, as he ended up with a result that is much larger than the correct sum.
