Does anyone know of a website where I can input 10 < X < 30 known values, and have it create an equation to give an also known result using each of the values at least once. Multiple uses of the same value are fine.
e.g. (on a smaller, simpler scale) I input A=3, B=2, C=5, D=10. Z=158.
And it outputs D*A*C + B^A = Z
Input values will likely all be integers with max 4 digits. Output will be a 15 digit integer. Being able to limit it to 'simple' functions (e.g. +,-,*,/,^,sqrt) is a benefit but not neccessary.
