Solve [(-6)*(-5+2)-(-3)]*(-4)+(4-9)=

$$[ ( - 6 ) \cdot ( - 5 + 2 ) - ( - 3 ) ] \cdot ( - 4 ) + ( 4 - 9 ) =$$

Evaluate

$$-89$$

Solution Steps

Add -5 and 2 to get -3.

$$\left(-6\left(-3\right)-\left(-3\right)\right)\left(-4\right)+4-9$$

Multiply -6 and -3 to get 18.

$$\left(18-\left(-3\right)\right)\left(-4\right)+4-9$$

The opposite of -3 is 3.

$$\left(18+3\right)\left(-4\right)+4-9$$

Add 18 and 3 to get 21.

$$21\left(-4\right)+4-9$$

Multiply 21 and -4 to get -84.

$$-84+4-9$$

Add -84 and 4 to get -80.

$$-80-9$$

Subtract 9 from -80 to get -89.

$$-89$$

Factor

$$-89$$
