I don't believe the solution you say is correct fits the original criteria in which two operands were to be combined with an arbitrary operation or operations. In the clarifying example it is shown that the operands can be repeated and more than one operation can be applied. In the solution...

Typo in this one lol 9 * 8 + 9 - 9 - 9 / 9 = 72 s/b 9 * 8 + 9 - 8 - 9 / 9 = 72 I used to know about quadratic equations and factoring but it all seems to be slipping away...lol

Given this example I take it the answer should be in the form a @ b = c...other numbers should not be brought in to the equation. I came up with: (a-(a/a))*(b+b/b) = c (1-(1/1))*(9+9/9) = 0 (3-(3/3))*(8+8/8) = 18 (9-(9/9))*(8+8/8) = 72 (9-(9/9))*(9+9/9) = 80 There probably are other solutions…
