Solve {l}{13*21}{15+2}{12+4+45}{12+(12*1)}

$$\left. \begin{array} { l } { 13 * 21 } \\ { 15 + 2 } \\ { 12 + 4 + 45 } \\ { 12 + ( 12 * 1 ) } \end{array} \right.$$

Sort

$$17,24,61,273$$

Solution Steps

Multiply 13 and 21 to get 273.

$$sort(273,15+2,12+4+45,12+12\times 1)$$

Add 15 and 2 to get 17.

$$sort(273,17,12+4+45,12+12\times 1)$$

Add 12 and 4 to get 16.

$$sort(273,17,16+45,12+12\times 1)$$

Add 16 and 45 to get 61.

$$sort(273,17,61,12+12\times 1)$$

Multiply 12 and 1 to get 12.

$$sort(273,17,61,12+12)$$

Add 12 and 12 to get 24.

$$sort(273,17,61,24)$$

To sort the list, start from a single element 273.

$$273$$

Insert 17 to the appropriate location in the new list.

$$17,273$$

Insert 61 to the appropriate location in the new list.

$$17,61,273$$

Insert 24 to the appropriate location in the new list.

$$17,24,61,273$$

Evaluate

$$273,\ 17,\ 61,\ 24$$
