Answer 1

To evaluate the statements about Bella's work on adding 836 and 94, let's consider them one by one:

1. **The sum of 836 and 94 should be 940.**
This statement is true. The correct calculation for 836 + 94 is 930.

2. **Bella set up the problem incorrectly. The 9 in 94 should be under the 3 in 836.**
This statement is true. When adding numbers, the digits must be aligned according to their place values. In this case, the 9 in 94 should be directly under the 3 in the tens place of 836 for proper alignment:
```
836
+ 94
```

3. **Bella set up the problem correctly. The largest digits in each number, regardless of place value, should line up.**
This statement is false. The numbers should be aligned according to their place values (hundreds, tens, units), not by the value of the digits.

4. **It is true that 836 + 94 = 1776.**
This statement is false. The correct sum of 836 and 94 is 930.

Based on this analysis, the two true statements about Bella's work are:
- The sum of 836 and 94 should be 940.
- Bella set up the problem incorrectly. The 9 in 94 should be under the 3 in 836.
