# Game of 24

1. 80
Kiwi Maxposted 3 years ago

Welcome Aboard!

Here are the rules to the game:

1. You are given 4 numbers, e.g. 1234 and must use each number, only once, to make 24
2. You may use addition, subtraction, multiplication & division as many times as you want
3. Once you've solved the problem from the post above, make your own by writing your 4 digits (you can only use numbers from & including 0-9

Note: There may be more than one solution to a problem. Feel free to post as many as you can think of!

Example: Use 1234 to make 24.
(4+2) x (3+1) = 24!

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

First problem below:

Make 24 using the numbers "6371"

Sounds interesting.
6 * 3 + 7 - 1 = 24

Tough one Ben! What's your solution? Is square root acceptable in this situation?

Can I do √9 x (4 x 2) + 0 = 24?

Kiwi Maxposted 3 years ago in reply to this

You cannot use square roots, sorry , however I'm not sure how you would do without it. Well done nonetheless for solving this one Brycekiguchi!

Ben, do you have a solution that doesn't involve using square roots?

(8*6)/(9-7) = 24

how about 7557

5. 81
brycekiguchiposted 3 years ago

Hmm... (7*7) - (5*5) = 24

((8/2) - 1) *8 = 24

Lol that's too easy. Sorry, didn't notice that 7+3+9+5 would do the trick. Haha! **embarrassed**

4! * 1 * (9/9) = 24

Beth, here's one just for you

The last time I was in a math class it was 1984. I can't tell you how proud I am of myself. lol

I didn't take a single math course in college. But I used to like math.

1984 was 9th gd. It was actually 1985, 10th gd. math. I think I'm done here. lol

1984
4*8-9+1

Beth37posted 3 years ago in reply to this

Those numbers have not been approved. You  might as well be using square roots.

wildernessposted 3 years ago in reply to this

You posted them - they must be approved.

Kiwi Maxposted 3 years ago in reply to this

Regarding 6666 - here's one solution:

6+6+6+6 = 24

Kiwi Maxposted 3 years ago

Next one to try is 1993!

brycekiguchiposted 3 years ago in reply to this

((√9 * 9) - 3) * 1 = 24

7889

Kiwi Maxposted 3 years ago in reply to this

You cannot use square roots Brycekiguchi. Only addition, subtraction, division or multiplication.

brycekiguchiposted 3 years ago in reply to this

Okay. Im outta here then!

Thanks, I had fun!

calculus-geometryposted 3 years ago in reply to this

I'll play square roots with you!  I'll even let you use logarithms

3. 0
calculus-geometryposted 3 years ago

7889 -->  √9 * 8 * (8-7) = 24, also
8 * log_(9-7) 8 = 8 * (log base 2 of 8) = 8*3 = 24
sorry kiwi I couldn't find a solution without square roots or logs, lol.

now try 11111111

yes, that's eight 1s.  you can use any mathematical operations you want

FitnezzJimposted 3 years ago in reply to this

[(1+1)^(1+1+1)]*(1+1+1)   if exponents are legal in this game.

and next is 3574

Kiwi Maxposted 3 years ago in reply to this

nice one Jim!

Kiwi Maxposted 3 years ago in reply to this

That's all right Cal

If addition, subtraction, multiplication or division doesn't work - feel free to get creative

4. 80
Kiwi Maxposted 3 years ago

I found 2 Solutions to 3574:

(3*4) + (5+7)

(5-4) + 7)) * 3

Here's another to try! -> 4567

calculus-geometryposted 3 years ago

(7+5)*(6-4) = 24

Got 23...28...26...hmm think I'm gonna sleep on it and find the answer tomorrow unless someone else gets there before me
