Hi Sarah Rebekah13;

I Post Sometime on the Help me forum.And noBody post on my Question.

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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi Sarah;

Forget the answer, was the method clear to you?
