Make 1,234 using the numbers 1, 2, 3, and 4 only

Can you do that? You can use any number up to two times only, and you have to use all the numbers. Okay? Any operations allowed, especially factorials, exponents, etc.

Re: Make 1,234 using the numbers 1, 2, 3, and 4 only

Hi;

If we can use any operation then the answer is 1234, concantenation used on 1,2,3,4.

Without that operation, I am not finding any yet. Maybe there are none.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

I didn't get the answer, I made it up myself.

Then we will go with the concat solution.

Thanks for that! But there might be another solution.

hi julianthemath

Where did you get the avatar?

I made it myself.

Made the still picture in Sketchpad, did a screen shot into Paint, then imported it to Flash and animated it as a GIF.

Hardest bit was getting it the right size (80 by 80) .

There are 1235 square roots in there.
