Solve {l}{(9+3)*15}{(9-6)*(10+7)}

$$\left. \begin{array} { l } { ( 9 + 3 ) \times 15 } \\ { ( 9 - 6 ) \times ( 10 + 7 ) } \end{array} \right.$$

Sort

$$51,180$$

Solution Steps

Add 9 and 3 to get 12.

$$sort(12\times 15,\left(9-6\right)\left(10+7\right))$$

Multiply 12 and 15 to get 180.

$$sort(180,\left(9-6\right)\left(10+7\right))$$

Subtract 6 from 9 to get 3.

$$sort(180,3\left(10+7\right))$$

Add 10 and 7 to get 17.

$$sort(180,3\times 17)$$

Multiply 3 and 17 to get 51.

$$sort(180,51)$$

To sort the list, start from a single element 180.

$$180$$

Insert 51 to the appropriate location in the new list.

$$51,180$$

Evaluate

$$180,\ 51$$
