4 + 4 + 4 + wortel/root 4=14

(4 x 4) - (4/4) = 15

vermeer · Post by **vermeer** » Fri Aug 26, 2005 2:59 pm

(4 x 4) + 4 - 4 = 16

( 4 x 4 ) + ( 4/4 ) = 17

44/Sqrt(4*4)=11

4 x 4 + 4 - wortel/root 4 = 18

44/4 + 4 + 4 = 19

4 (tot de macht 3) = 64 - 44 = 20

That requires 5 fours

(4*4*4-44=20)
4*(4+(4/4)) = 20, and
(44 - sqrt4)/sqrt4 = 21

4 x 4 + 4 + sqrt4 = 22

But Magpie - if you do it that way, I can't steal noogie's extra 4 for my "13"....

(44 + sqrt4) / sqrt4 = 23

24 = 4! + (4-4)/4

(BTW, 13 was still missing: 13 = 4!/sqrt 4 + 4/4.)

4+(4-4)/4=4

24=4*4+4+4

No, 4! = 1 x 2 x 3 x 4 = 24.
So 4! +(4-4)/4 = 24 + 0 = 24.
(The notation n! means n factorial, that is: all integers from 1 up to n multiplied.)
