Solution Steps

Add 900 and 1000 to get 1900.

$$sort(1900+2000+50,200+100+2800+700,350+260)$$

Add 1900 and 2000 to get 3900.

$$sort(3900+50,200+100+2800+700,350+260)$$

Add 3900 and 50 to get 3950.

$$sort(3950,200+100+2800+700,350+260)$$

Add 200 and 100 to get 300.

$$sort(3950,300+2800+700,350+260)$$

Add 300 and 2800 to get 3100.

$$sort(3950,3100+700,350+260)$$

Add 3100 and 700 to get 3800.

$$sort(3950,3800,350+260)$$

Add 350 and 260 to get 610.

$$sort(3950,3800,610)$$

To sort the list, start from a single element 3950.
