Hi there,
I could just give you the answer, but I would like to show you a trick so you can work it out yourself the next time this comes up:
Whenever you have a partial number after the decimal point, even the places out before you begin:
Which is easier to figure out:
4.82+12.7
... or:
12.70
+ 4.82
-------
When you see it like that, it is stone simple, eh? Just do the addition as if the decimal wasn't there at all. Adding that 0 after the 7 just makes it process better when you look at it.
So:
12.70
+ 4.82
-------
17.52

I'm not good at math, but I'm pretty sure it's:
21.02
