### Puzzle of 28

There is a very Popular and in fact quite a Fantastic Puzzle of Sixes like this . . .

N  N  N  =  6

Insert Mathematical Symbols and make Equality Equations for N = 0 to 9

This is quite a Beauty, and adds another Feather to the Cap of Number Six, which anyway is a Perfect Number.

This set me wondering if the next Perfect Number 28 will also have such Fantastic possibility . . .

N   N   N   N   =   28

. . .   and I have found it to be possible for 2 to 9 except 6.

Would Our Members like to crack this, for the Numbers as above and also for 0. 1 and 6 ?,

28 PUZZLES

By way of a little Guidance . . .  here are some Examples . . .

For the 6 Puzzles . . .     7 - (7/7) =  6

For 28 Puzzles  . . .       (2 + 2)! + 2 + 2 =  28

Let N!! be the double factorial of N

6!! = 2*4*6 = 48

6!! - (6 + 6)/.6 = 28

- - - - - - - - - - - - - - - -

48 - 12/.6 =

48 -  120/6 =

48 - 20 =

28
