From pie to numbers (Posted on 2015-12-27) Difficulty: 3 of 5
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.

Please show your list.

Some Thoughts re(6): hint- a DejMar I'll chip in 59 Comment 14 of 14 |
(In reply to re(5): hint- a DejMar I'll chip in 59 by Dej Mar)

Very interesting!Using your table, in which there is no gap over 10 (80 - 90) one can fill in by adding or subtracting numbers 1, 3-1, 3, 3+1, 3!-1.

Facing larger gaps we have 3!, 3!+1, 13, 31 and more, like (3!)!!=48 (3!)!!!=18 !(3+1)=9 etc
