$$6,12,18,42$$

Insert 9 to the appropriate location in the new list.

$$6,9,12,18,42$$

Insert 21 to the appropriate location in the new list.

$$6,9,12,18,21,42$$

Insert 3 to the appropriate location in the new list.

$$3,6,9,12,18,21,42$$

Insert 9 to the appropriate location in the new list.

$$3,6,9,9,12,18,21,42$$

Insert 21 to the appropriate location in the new list.

$$3,6,9,9,12,18,21,21,42$$

Insert 3 to the appropriate location in the new list.

$$3,3,6,9,9,12,18,21,21,42$$

Insert 3 to the appropriate location in the new list.

$$3,3,3,6,9,9,12,18,21,21,42$$

Insert 7 to the appropriate location in the new list.

$$3,3,3,6,7,9,9,12,18,21,21,42$$

Insert 1 to the appropriate location in the new list.

$$1,3,3,3,6,7,9,9,12,18,21,21,42$$

Insert 1 to the appropriate location in the new list.

$$1,1,3,3,3,6,7,9,9,12,18,21,21,42$$

Insert 7 to the appropriate location in the new list.

$$1,1,3,3,3,6,7,7,9,9,12,18,21,21,42$$

Evaluate

$$12,\ 18,\ 42,\ 6,\ 9,\ 21,\ 3,\ 9,\ 21,\ 3,\ 3,\ 7,\ 1,\ 1,\ 7$$
