Fun maths problem...

[Koing]

Object: To make 24 (putting 2 and 4 together is not the way!)

You have:

1, 3, 4 and 6

You can: *, /, +, -

You numbers 1, 3, 4 and 6 at ONLY ONCE.

You can also use the result in the next calculation. E.g. 4-1 = 3. Now you can use 3 (result from using 4 and 1) with the remaindnig numbers.

Harder then you think.

Koing

Sorry about that. None of you are correct. You can only use the numbers ONLY ONCE and the result of what you make once.

(1+3) * 6 / 4 * 4

3 * 4 * (6 / 3) / 1

3 * 4 * (6 / 3) * 1

3 * 4 * 6 / 3 / 1

3 * 4 * 6 / 3 * 1

3 * 4 * (3 - 1) / 6 * 6

(6 - 1) * 4 + 3 + 1

(6 - 3) * 4 * (3 - 1)

(6 - 1) * (6 - 1) - (4 - 3)

4 * 6 / (3 / 3) / 1

(6^2 - 4^2) + 3 + 1

1, 3, 4, and 6

 

[AsianriceX]

1+3=4
4-4=0
0+4=4
4*6=24

right?

 

[AccruedExpenditure]

(1+3) * 6 / 4 * 4

 

[oniq]

2 then 4

I didn't see the repost, but this was an extremely easy problem. There are several solutions though.

Example


3 * 4 * (6 / 3) / 1

3 * 4 * (6 / 3) / 1

That isn't right.

You used the 3 twice. You used it in the 3 * 4 to make 12. Then you used it again to do 6 / 3.

Here is a better example to highlight what you can do.

4-3 = 1
Now you can use the result 1 with remaining initial numbers (1, 6) that are left.

Ps didn't know it was a repost and I'm sure people would like a go at this.

Nope.

You used the 4 twice here.

At that stage you only have 0 and 6 left. You used the 1, 3 and 4 up.

Yeah I know sorry I screwed it up originally 🙁

You can only use it ONLY ONCE now and whatever results you made.

(6^2 - 4^2) + 3 + 1 ?

That is wrong.

You used 2 twice and you don't have 2 in the question but good try.

You only have

1, 3, 4 and 6.

Koing

Would it help if I stated it as (6² - 4²) + 3 + 1 ?

Or did you mean that I used two of the numbers twice?

 

[BullsOnParade]

you can't square any numbers

hello McFly, you can't use a 2, even as an exponent.

 

[BullsOnParade]

Koing are you sure its a 6 and not a 9 ?

 

[Drakkon]

(14-6)*3 = 24

we used to just hit the cards without seeing the number and figure it out in the
3 seconds you had to give your answer.

 

[Lonyo]

Hmm

 

[Hector13]

6 * 4 = 24

or are you not explaining the part about having to use each number at least once?
