    I confirm the result of the original author. I could not find a
    "normal" solution even though I tried potentiating and
    allowed complex intermediate results. The best approximation is:
    1+(2-3^4^(5/6/7))^-8+9 = 10958.00205791. A formula that works but
    does not conform to the rules is: 0.1*(-2+3+4+5^6)*7+8+9 = 10958.

      If the square root is allowed, this does work. I think it was the simple operators and exponents, but this does indeed work.

    Sounds like a bunch of Common Core BS to me. 4 = 2x8-12. The simple answer is 2x2 equals 4.
    Maybe just maybe mathematics is not the key to the Universe with the exceptions of 1s an 0s in certain series of repetitiously?

    "Natural numbers from 0 to 11111 - except one: 10958 - are written in terms of 1 to 9 in two different ways. The first one in increasing order of 1 to 9, and the second one in decreasing order. This is done by using the operations of addition, subtraction, multiplication, division and potentiation.

    11*(11-1)^(1+1+1)-[((1+1+1+1)*11)-1-1]=10958, quite complicated and possibly too many steps to solving it, right.
