This is not an assignment. I just want to see who the first one is that can figure this out because it's always fun to show off your intelligence, right? And I know that none of you have anything better to do.

You have the numbers 2, 3, and 5. You can use any combination of algebraic functions so that you reach the number 19. This includes: square roots, division, factorials, exponents, etc. However, you can only use these numbers once. So, lets say the number was 17 instead of 19: you would do 5 times 3, then add 2 to get 17. But, 19 is a little trickier.

So, let's see how smart the pit is. Begin thinking!

EDIT: You HAVE to use all the numbers.

5 squared = 25

2 x 3 = 6

25 - 6 = 19

2 x 3 = 6

25 - 6 = 19

#3

Nah, you cant use 2 more than once

EDIT: 5^2, that is using the two once. 3X2 is twice.

I didn't.

I didn't.

look at my edit

#9

look at my edit

I didn't use 2 twice though.

I used 5 twice

#10

5 squared = 25

2 x 3 = 6

25 - 6 = 19

(5^2)-3! then?

#11

5^2 = 25

3! (3x2x1) is 6

25-6=19. It says we can use factorials in the question.

3! (3x2x1) is 6

25-6=19. It says we can use factorials in the question.

#12

^ Haha, thread over. Riveting.

#13

(5^2)-(2*3) = 19

#14

^^^this is correct. Factorials are the way to go.

#15

5^2 - 3!

#16

Do your own fucking homework, TS. After all, I just did mine.

#17

#18

fuck math. and bitches. and da po po.

vaginaboob.

vaginaboob.

#19

Okay, I have a new challenge. Get 21. I have the solution, hoping there's no other one.

#20

(5+2)x3

#21

5^2 - 3! = 19

(5+2) (3) = 21

Okay, I have a new challenge. Get 21. I have the solution, hoping there's no other one.

(5+2) (3) = 21

Dammit. I'll be back with a new one.... SOON

EDIT: 23 ... find that.

EDITDOS: Or 5.

2 + 3 = 23

#28

5^2 - 3! = 19

#29

2 + 3 = 23

gotta use 5 going by my rules!

EDIT: is there a solution to 23 eastwinn?

#30

2 + 3 = 23

You got me for a second :P

How about this:

0: 5 - 3 - 2

1: (5-3)/2

2:

3: 2^3 - 5

4: 3^2 - 5

5: (3-2)*5

6: 5 + 3 - 2

7: 2*5 - 3

8:

9:

10: 5 + 3 + 2

11:

12:

13: 2*5 + 3

14: 3^2 + 5

15: 5!/(3! + 2)

16: 2*5 + 3!

17: 3*5 + 2

18: 5!/3! - 2

19: 5^2 - 3!

20: (2+3)!! + 5

21: (5+2)*3

22: 5^2 - 3

23: 5!! + 2^3

24: 5!/(3+2)

25:

Okay UG, let's fill this in.

5^2=25

25-3 = 22. Easy fill in.

For 27, just add 2 instead of subtracting, you should do all of the basic math ones like that, to conserve posts.

Gotta use all the numbers. Ill put that in OP.

Now you're being obtuse. The point is to look for elegant solutions
