We need to add 174812 plus 1247612. First, let's set up the problem by aligning the numbers vertically by place value, with the larger number on the bottom.
Now let's start adding from the rightmost column. In the units place, we have 2 plus 2 equals 4. In the tens place, we have 1 plus 1 equals 2. These are straightforward additions with no carrying needed.
Now we move to the hundreds column. We have 8 plus 6 which equals 14. Since this is greater than 9, we write down 4 in the hundreds place and carry the 1 to the thousands column.
Let's complete the remaining columns. In the thousands place: 4 plus 7 plus the carried 1 equals 12, so we write 2 and carry 1. In the ten thousands place: 7 plus 4 plus the carried 1 equals 12, so we write 2 and carry 1. Finally, in the hundred thousands place: 1 plus 2 plus the carried 1 equals 4. The final answer is 1,422,424.
Therefore, 174,812 plus 1,247,612 equals 1,422,424. We have successfully solved this addition problem using the vertical addition method with proper carrying. This systematic approach ensures accuracy when adding large numbers.
