The answer is: 196.328992
To solve this, both numbers must be aligned in such way that the decimal point are aligned, and then we add from left to right:
Then, the 992 isn't adding anything so remains the same.
3 + 5 = 8 so we can put this directly
4 + 8 = 12
then we do the same as when we're adding whole numbers, we put the unit and take the 1 to the next place.
The next place have 0 + 2 = 2 but also have the 1 from before: 2 + 1 = 3
Now we need to add 12 + 184
2 + 4 = 6 and 1 + 8 = 9:
Then: 12 +184 = 196
