Hello,

your post is formatted in such a way, that I start thinking that you are not interested to learn the solution

(and even are not going to see or read it), but only interested to get the number (the answer) to input it to the system.

Please write me if my understanding is correct.

If not, if you do not want to produce such an impression, then please format your post accordingly.
