basically you gotta get all the numbers 1-100.

ok so i need to find how to = the numbers 85, 86, 91, 93, 99 or find out if they are possible or not using

the numbers 1, 2, 3, and 4
addition, subtraction, multiplication, division
powers, factorials, square root, parentheses

in example if i wanted the number 22

(3!+4^2)/1 = ((3x2x1)+4^2)/1

but i only need 85 86 91 93 and 99

These are recreational problems - so keep playing around.

I do not think you can prove that a solution does not exist - except for upper bound.
