Given how simple this is, I'm not sure if it has been asked before. But I did try searching everywhere and didn't come up with anything. It is based on these two questions I happened to stumble upon:
My question is similar - using 1, 2, 3, 4, and 5, and only the basic operators (addition, subtraction, multiplication, and division), what is the smallest possible positive integer you cannot make?
The use of brackets is allowed. You must use every single one of the five digits in each case. Unlike the other two questions though, factorials and exponentiation are not allowed, therefore I think this will pose a lot more of a challenge, and make finding the solution more plausible.
Also, just in case it isn't clear, concatenation is also not allowed, and you have to use all the five numbers exactly once for each case. The order of use of the numbers does not matter.
I've tried making it to 100, but got stuck at a certain number which I think might be the solution.
Given how simple this puzzle seems, I apologize in advance if something like this has already been posted.
