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.
