### Instruction: Write $4.3+3.88$ as a decimal.### Response: I need to add two decimals, so I should line up the decimal points and add from right to left.
I can write the numbers like this: $4.30 + 3.88$.
Starting from the rightmost column, I have $0+8=8$.
In the next column, I have $3+8=11$.
Since 11 is more than 10, I need to carry a 1 to the next column and write 1 in the answer.
In the next column, I have $4+3=7$, plus the 1 that I carried, so $7+1=8$.
I write 8 in the answer.
Finally, I bring down the decimal point in the same place as the original numbers.
So the answer is $8.18$.
