Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Set up the numbers for addition in a vertical format, aligning the rightmost digits.
  • Step 2: Add each column starting from the right, keeping track of the carryover.
  • Step 3: Continue the addition for all columns, incorporating any carryover into the next left column.

Now, let's work through the addition process:

Add the units column: 1+7=81 + 7 = 8. No carryover occurs here.

Next, add the tens column: 8+1=98 + 1 = 9. Still, no carryover is involved.

Then, add the hundreds column: 7+4=117 + 4 = 11. Because this is more than 9, we write down 1 and carry over 1 to the next column.

Finally, add the thousands column: 2+8=102 + 8 = 10, plus the 1 carried over gives 11. Thus, we write down 11.

Therefore, the sum of the numbers is 11198 \boxed{11198} .
