If not, the problem does not exist. First of all, 9 must be placed at the bottom, so the remaining two and 9 add up to 16, the remaining two =7, and 1 to 8 add up to 7, only 1+6, 2+5, 3+4. Look at the top two lines, which add up to the following figures. It is out of the question.

If possible, it does not exist. First of all, it can be seen that Formula 3 is only 2 larger than Formula 1 and 2 larger than Formula 2 1. There can be no+and * between formula 1 and formula 2.
