3.4+2.3=5.7 how is this possible ??

3.4+2.3= 12 + 6 so its 18 

It seems there might be a misunderstanding in the way the addition of decimals works.

### Correct Explanation:
When you add 3.4 and 2.3, you are adding the numbers as decimals, not as individual digits.

\[
3.4 + 2.3 = 5.7
\]

Here's a breakdown:
- **3.4** means 3 + 0.4
- **2.3** means 2 + 0.3

When you add these:
\[
3 + 2 = 5
\]
\[
0.4 + 0.3 = 0.7
\]

So:
\[
3.4 + 2.3 = 5 + 0.7 = 5.7
\]

### Misunderstanding:
It seems you tried to add the digits individually as whole numbers:
- 3 + 2 = 5 (this part is correct)
- 4 + 3 = 7 (this is also correct, but it doesn't become 12 and 6, and there is no carrying over like in multiplication or larger sums)

There is no "carrying" involved in simple addition unless the sum of the decimal places exceeds 10. If the numbers were added as whole numbers like 34 + 23, you would get 57, but since we are dealing with decimals, the answer is 5.7.
