To solve this problem, we'll perform vertical addition:
After adding each column and managing the carries appropriately, the resulting sum of these numbers is 421.
Therefore, the solution to the problem is .
421
To solve the problem of adding 285 and 146, we'll use vertical addition with regrouping. Here are the steps:
Step 1: Write the numbers vertically, aligning by their place values:
Step 2: Begin addition from the rightmost column (units):
Step 3: Move to the tens column, adding the carry:
Step 4: Finally, add the hundreds column:
The final sum reads:
Therefore, the sum of 285 and 146 is , which matches choice 2 in the provided multiple-choice options.
Therefore, the solution to the problem is .
431
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Align numbers:
Step 2: Begin with the units place:
8 (units from 378) + 5 (units from 455) = 13.
Write down 3 in the units place, and carry over 1 to the tens place.
Step 3: Move to the tens place:
7 (tens from 378) + 5 (tens from 455) + 1 (carried over) = 13.
Write down 3 in the tens place, and carry over 1 to the hundreds place.
Step 4: Finally, add the hundreds place:
3 (hundreds from 378) + 4 (hundreds from 455) + 1 (carried over) = 8.
Write down 8 in the hundreds place.
The final sum is, therefore:
Therefore, the solution to the problem is .

To solve this problem, we will perform vertical addition on the two numbers, 589 and 263:
Combining our results, the sum of 589 and 263 is .
852
To solve this problem, we'll follow these steps:
Step 1: Write the numbers one under the other, aligning their digits by place value.
Step 2: Add the digits from the rightmost column to the left, carrying over where needed.
Detailed Steps:
Step 1: Begin with the units place. Add the digits in the units column: . Write down 1 in the units column and carry over the 1 to the tens column.
Step 2: Move to the tens column. Add the digits along with the carried over value: . Again, write down 1 in the tens column and carry over the 1 to the hundreds column.
Step 3: In the final hundreds column, add: . Write down the 9 in the hundreds column as there are no more digits to add.
The final result by putting all these together is: .
Therefore, the sum of 677 and 234 is
