		int n1 = keyBoard.nextInt();
		int n2 = keyBoard.nextInt();
		int sum=0;
		System.out.print("Sum = ");
		for(int i=n1;i<n2;i++) {
			sum+=i;
			if(i>=0) {
				System.out.print(i+" + ");
			}else {
				System.out.print("("+i+") + ");
			}
		}
		sum+=n2;
		if(n2>=0) {
			System.out.print(n2);
		}else {
			System.out.print("("+n2+")");
		}
