Question 207081
<font face="Garamond" size="+2">


Nope, there is no 'formula' for this.  You just have to use your imagination and come up with ways to put those 4 numbers together in thirty-one different ways so that you come up with the results from 0 through 30.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 9 \times (5 + 1 - 6) = 9 \times 0 = 0]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (5 + 6) - (9 + 1) = 11 - 10 = 1]


and so on...


Sorry, but you are just going to have to do some thinking.  What a concept!
