### Instruction: What is 0.3 more than 29.8?### Response: I need to add 0.3 to 29.8.
To add decimals, I can align them by their decimal points and add the corresponding digits from right to left.
If one of the numbers has fewer digits than the other, I can add zeros as placeholders to make them the same length.
So I can write 29.8 as 29.80 and 0.3 as 0.30.
Then I can add them like this:

  29.80
+  0.30
-------
  30.10
