Solve {l}{5*(-20-7)}{109*(-7)-9*(-7)}

$$\left. \begin{array} { l } { 5 \cdot ( - 20 - 7 ) } \\ { 109 \cdot ( - 7 ) - 9 \cdot ( - 7 ) } \end{array} \right.$$

Sort

$$-700,-135$$

Solution Steps

Subtract 7 from -20 to get -27.

$$sort(5\left(-27\right),109\left(-7\right)-9\left(-7\right))$$

Multiply 5 and -27 to get -135.

$$sort(-135,109\left(-7\right)-9\left(-7\right))$$

Multiply 109 and -7 to get -763.

$$sort(-135,-763-9\left(-7\right))$$

Multiply 9 and -7 to get -63.

$$sort(-135,-763-\left(-63\right))$$

The opposite of -63 is 63.

$$sort(-135,-763+63)$$

Add -763 and 63 to get -700.

$$sort(-135,-700)$$

To sort the list, start from a single element -135.

$$-135$$

Insert -700 to the appropriate location in the new list.

$$-700,-135$$

Evaluate

$$-135,\ -700$$
