https://code.sololearn.com/c3NFgbWCU5T8/?ref=app This is a program I wrote in Python. You could use the same method to add without + in Java.. My solution (maybe not the desired solution, but the one I can up with) .. My solution was to for loop thru X and Y number of times, adding a number to an array each time.. the sum of X + Y becomes the length of the array. For Example.. - X=5 Y=3 EmptyArray=[] for(int i=0; i<X; i++){ add I to EmptyArray } for(int i=0; i<Y; i++){ add I to EmptyArray } Sum = length(EmptyArray);

//this is probably cheating: public class Program { public static void main(String[] args) { System.out.print(5-(-5));//5+5 //outputs 10 } }
