Solve 2-7+15(-15-19)+4(25-18)+8][12-19-(19+15)]

$$2 - 7 + 15 ( - 15 - 19 ) + 4 ( 25 - 18 ) + 8 ] [ 12 - 19 - ( 19 + 15 ) ]$$

Evaluate

$$-479$$

Solution Steps

Subtract 7 from 2 to get -5.

$$-5+15\left(-15-19\right)+4\left(25-18\right)+8$$

Subtract 19 from -15 to get -34.

$$-5+15\left(-34\right)+4\left(25-18\right)+8$$

Multiply 15 and -34 to get -510.

$$-5-510+4\left(25-18\right)+8$$

Subtract 510 from -5 to get -515.

$$-515+4\left(25-18\right)+8$$

Subtract 18 from 25 to get 7.

$$-515+4\times 7+8$$

Multiply 4 and 7 to get 28.

$$-515+28+8$$

Add -515 and 28 to get -487.

$$-487+8$$

Add -487 and 8 to get -479.

$$-479$$
