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.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Hi Sarah;

Forget the answer, was the method clear to you?
