Solve {l}{20-30}{30+40}{50-50}{50-6}

$$\left. \begin{array} { l } { 20 - 30 } \\ { 30 + 40 } \\ { 50 - 50 } \\ { 50 - 6 } \end{array} \right.$$

Sort

$$-10,0,44,70$$

Solution Steps

Subtract 30 from 20 to get -10.

$$sort(-10,30+40,50-50,50-6)$$

Add 30 and 40 to get 70.

$$sort(-10,70,50-50,50-6)$$

Subtract 50 from 50 to get 0.

$$sort(-10,70,0,50-6)$$

Subtract 6 from 50 to get 44.

$$sort(-10,70,0,44)$$

To sort the list, start from a single element -10.

$$-10$$

Insert 70 to the appropriate location in the new list.

$$-10,70$$

Insert 0 to the appropriate location in the new list.

$$-10,0,70$$

Insert 44 to the appropriate location in the new list.

$$-10,0,44,70$$

Evaluate

$$-10,\ 70,\ 0,\ 44$$
