13 + 13 - 6/3 = 24
6 * (13/13 + 3) = 24
(3+13/13)! = 24
(6 - 3 + 13/13)! = 24
(13 - 6 - 3)! = 24
you didnt say use them all.
these are all different.

(13+13) - (6/3) = 24
6 * (3 + 13/13) = 24
13 - (6/3) + 13 = 24
(3 + 13/13) * 6 = 24
(-6/3) + 13 + 13 = 24
Edit: The last three equations are really just rearrangements of the first two equations.
If you can use factorial (!) then you have some more possibilities:
(3 + (13 - 13)!) * 6 = 24
6 * (3 + (13/13)!) = 24
(6 - 3 + (13/13))! = 24
((6 * (13 - 13))! + 3)! = 24
I like the last one because it uses all the four numbers but still manages to make 4! in a creative way.

Here are 5 different ways using ALL the numbers:
1) (3 + 13/13)*6
2) 13 + 13 - 6/3
3) (3 + (13 - 13)!)*6
4) (6 - 3 + 13/13)!
5) [3 + {arcos(13/13)}!]*6

In Puzzling's answers, #1, #3, and #5 are the same; #2 and #4 are the same . So that is only TWO different equations.

13 + 13 - 6 / 3
there's an obvious one

Puzzling got 'em all. Good job. Fun question.

(13+13)-(6/3)=24
-(6/3)+(13+13)=24
-6/3+13+13=24
13+(-6/3)+13=24
6/-3+13+13=24
