Use two 8s and two 3s to make the number 24

$begingroup$



Use two $8$s, two $3$s, and basic arithmetic operators ($ +, -, times , div$, parentheses) to make the number $24$.



(You may not join numbers together to form new numbers, like $ 8, 3rightarrow 83$)




I don't know how to start besides just trying to find the correct answer. Is there a way you can make this equation through small steps or I should just bruteforce it?

Here is a solution that uses only "elementary" operations (addition, subtraction, multiplication, and division).




$8 div (3 - (8 div 3))$ (or alternatively $frac{8}{3 - frac{8}{3}}$)
$= 8 div frac{1}{3}$
$= 24$




If we allow square roots, a simpler solution is possible.




$sqrt{8 times 8 times 3 times 3}$
$= 8 times 3$
$= 24$




In fact, there are many more solutions if you allow more operations.
