I take it that you can't answer the question. I have read the instruction. I am looking for someone that my have experience the same problem that can provide appropriate assistance.

I am not crying, thanks for your reply. It really helped.

That is correct so back to the original problem, which is a little different.

* + - + 43628

example problem - 234* - 482/++

234 * - 482/++ (first 3 4 * is evaluated)
2 12 - 482/++ (next 2 12 - is evaluated)
-10482/++ (then 82 / is evaluated and replaced)
-1044 + + (next 4 4 + is...
