To add multi-digit numbers quickly and accurately, follow these steps:
1. **Line up the numbers**: Write the numbers vertically, aligning them by place value (ones, tens, hundreds, etc.).
2. **Start from the right**: Begin adding from the rightmost column (the ones).
3. **Carry over if needed**: If the sum of a column is 10 or more, write down the last digit and carry over the 1 to the next column on the left.
4. **Move left**: Repeat the process for each column, moving left until all columns are added.
5. **Double-check**: Finally, go over the addition to make sure everything is correct.
Practice this method to get better and faster!

To add multi-digit numbers quickly and accurately, first, line up the numbers by their place values (ones, tens, hundreds) so they align properly. Start adding from the rightmost column (the ones place) and move left, carrying over any extra value if the sum exceeds ten. For example, if you add 8 and 7 in the ones place, you write down 5 and carry over 1 to the tens place. Continue this process for each column, and double-check your work to ensure accuracy. Practicing this method helps improve both speed and accuracy in addition!
