How do you make 29 with only using the numbers 1 2 3 4? I have tried a lot of solutions and please remember that you can't use the number 5

  • $\begingroup$ What operations are allowed to be used? How many times can each digit $1,2,3,4$ be used? Must they all be used? Is concatenation (e.g. $21,13$) allowed? I'm voting to close as "too broad" until more detail of the rules is provided. $\endgroup$ – Rand al'Thor Sep 22 '19 at 12:45
  • $\begingroup$ It says numbers, not digits. Each number once goes without saying. But the list of valid operations is clearly missing. $\endgroup$ – Florian F Sep 22 '19 at 14:18

Here's several ways:

$31-\frac42$
$4!+3!-2+1$
$3^{2+1}+\sqrt{4}$
$2^{4+1}-3$
$42-13$

One of the ways could be :-

$2^2+3^2+4^{3-1}$

  • $\begingroup$ It is likely that each number should appear only once, otherwise there are a lot of very obvious answers. $\endgroup$ – Arnaud Mortier Sep 22 '19 at 12:47

    $\begingroup$ @ArnaudMortier That’s more a fault of the question than of the answer, though. $\endgroup$ – Lawrence Sep 23 '19 at 0:31
