Hi Sarah Rebekah13;

Probably no one saw it. Over here almost everything gets a response from someone. Lots of math brains here.

I can't speak for everyone but that is usually the case when I don't respond. Or because someone else has already done a better job then I could do.
Let's do your problem.
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
5 + 9 =14 put down the 4 and carry the 1
1
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
4
1 + 2 = 3 it is not bigger than 9 so no carry, just write it down.
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
. 3 4
0 + 0 = 0
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
0 . 3 4
8 + 7 = 15 put down the 5 carry the 1
1
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
5 0 . 3 4
1+1 = 2
$1 7 0 . 0 9
+ 8 0 . 2 5
---------------
$ 2 5 0 . 3 4
$ 250.34 is the answer!
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Hi Sarah;
Forget the answer, was the method clear to you?
