Understanding Left-to-Right Addition
Left-to-right addition is a method where you start adding from the leftmost digits of the numbers. Let's break down the addition of 346 and 278 step-by-step.
Step 1: Add the Hundreds Place
- The hundreds digit of 346 is 3.
- The hundreds digit of 278 is 2.
- Adding these gives: 3 + 2 = 5.
Step 2: Add the Tens Place
- The tens digit of 346 is 4.
- The tens digit of 278 is 7.
- Adding these gives: 4 + 7 = 11.
- Here, we have a carry of 1 (since 11 is two digits).
Step 3: Add the Units Place
- The units digit of 346 is 6.
- The units digit of 278 is 8.
- Adding these gives: 6 + 8 = 14.
- Now, add the carry from the previous step: 14 + 1 = 15.
- Again, we have a carry of 1 (since 15 is also two digits).
Combining All Parts
- Now, let's put together the results from each step:
- Hundreds: 5
- Tens: 1 (from carry), plus the next digit: 5 (from 11).
- Units: 5 (from 15), plus the next digit: 1 (from carry).
So, the final arrangement is 624.
Conclusion
The result of 346 + 278 using left-to-right addition is 624, making option 'C' the correct answer.
