Hey guys,

I need some help.

Lets say im trying to code a simple game, where I have 4 random numbers, and the player has to:

1) Add, subtract, multiply or divide all 4 numbers with each other to get the number 21.

2) Number can only be used once.

How would i go about with that algorithm?

Thanks, have a nice day
