Do I really need to do this?
I'm trying to find all the combonations of four certain numbers to make a scratch project, but is there an easier way???
Math Trick of the Week: Choose any three digit number that's one digit is at least 2 less that the tens digit and the tens digit at least 2 less than the hundreds. Then, reverse the digits and subtract. Then, reverse the digits in the answer and add. You should get 1089.

Re: Do I really need to do this?
I'm trying to make a math 24 game solver but the only way I can think of doing it is to find how many combonations there are with + - * and /. But there has to be an easier way, right?

Re: Do I really need to do this?
In order to make a project, I need to find all the combonations of 4 numbers. But can a few scripts help me find it easier??

Oh! Thanks. 
Now, excuse me for being slightly ignorant, but do you mean "combinations" as in "ways to add, subtract, multiply, and divide them" or "ways to order them to make a larger number?"

I'm afraid there is pretty much only one way: use a script for every possible combination of adding, subtracting, multiplying, and dividing them. Sorry I can't be of much help.

Yes, and then switch it up every time.

Re: Do I really need to do this?
Just so you know, 24 is a math game with cards. Each card has 4 numbers on it. You have to add, subtract, multiply, and divide those numbers to try to make "24".

Re: Do I really need to do this?
Yes, I know that. So then I'm going to switch it up to maybe (Number+Number+Number-Number)
