Is there a way you can get the number 5 from the numbers 6, 7, 8, and 9 using only addition, subtraction, multiplacation, and division, without combining two numbers e.g. using the 6 and 7 to create 67. Exponents, factorials, and trig functions are not allowed. If there is no way to do this, is there a way to prove that it is impossible? Thanks if you answer.
The code in my answer to your other question gives one more solution (after curating the output by hand)
7*(8-6)-9=5 (Bruno's solution) (7+8)/(9-6)=5.0 (Oscar's solution) 8-6/(9-7)=5.0 8/6*9-7=5.0 (Zach's solution)
