Worked Example
Problem: 12.46 + 5.8
- Align decimal points: 12.46 + 5.80— Append a zero to 5.8 so both numbers have two decimal places.
- Add hundredths: 6 + 0 = 6— No regrouping needed.
- Add tenths: 4 + 8 = 12, write 2 carry 1— Carry 1 to the ones column.
- Add ones: 2 + 5 + 1 = 8— Include the carried 1.
- Add tens: 1 + 0 = 1— Bring down the 1.
Answer: 18.26
Frequently Asked Questions
Lining up decimal points ensures you add digits with the same place value — tenths to tenths, hundredths to hundredths.
Yes. Writing 3.4 as 3.40 does not change its value but makes the hundredths column visible.
Exactly the same. When a column sums to 10 or more, write the ones digit and carry 1 to the next column to the left.
