Rules: 1: You HAVE to use only four fours, and the allowed operations. 2: If the expression does not equal the remix number, do not remix that person. 3: I prefer you to try to make the number with the smallest impurity level you can. 4: Be creative! 5: Read the following CAREFULLY to understand impurity levels(inspired by David Wheeler's four fours answer key) Impurity levels are as follows: 0 - Basic four operations, parentheses, square root, factorial, exponent (4^(4) is allowed), digit combining (44 is allowed), decimal point(.4 is allowed) 1 - Overline(0.4_ = 4/9 (is allowed)) 2 - gamma function (gamma(x) = (x - 1)!) and subfactorial(google it if you don't know what it is, because I don't know how to explain it) 3 - arbitrary roots( cbrt(4) and 4root(4) is allowed) 4 - multifactorials (where you factorialise multiple times) 5 - square and cube functions (sq(x) = x² and cb(x) = x³) 6 - floor, ceiling, rounding 7 - sin, cos, tan, 10^n
why do i have an obsession with subfactorials
