 From pie to numbers (Posted on 2015-12-27)
Let us use the first 3 digits of PI, i.e. 3,1,4 to create numbers from 1 to 50, using only basic math. operators.
Not all the digits must be used, but none can be repeated.

Examples (out of this range): 52= 13*4; 65=4^3+1; 84=14*3!

Only few numbers cannot be achieved.

It was my original intention not to define strictly what symbols are excluded and my list of solutions did not include !n (a.k.a. subfactorial ), and used n!! only twice  39= 31+4!!    and 45= 3*(4+1)!! , 46 and 50 absent.

@ Dej Mar (and other solvers ) a bonus task:

How far can you go, accepting all operators needed for 1-50, but introducing no new ones?       e.g:

51= !5 + !4 -!3

52=13*4

53=!(3!)/(4+1)  etc
