Solve (-1+2)(3-5(-1)-2(3(-1)-2)(-1-2)

$$( - 1 + 2 ) ( 3 - 5 ( - 1 ) - 2 ( 3 ( - 1 ) - 2 ) ( - 1 - 2 )$$

Evaluate

$$-22$$

Solution Steps

Add -1 and 2 to get 1.

$$1\left(3-5\left(-1\right)-2\left(3\left(-1\right)-2\right)\left(-1-2\right)\right)$$

Multiply 5 and -1 to get -5.

$$1\left(3-\left(-5\right)-2\left(3\left(-1\right)-2\right)\left(-1-2\right)\right)$$

The opposite of -5 is 5.

$$1\left(3+5-2\left(3\left(-1\right)-2\right)\left(-1-2\right)\right)$$

Add 3 and 5 to get 8.

$$1\left(8-2\left(3\left(-1\right)-2\right)\left(-1-2\right)\right)$$

Multiply 3 and -1 to get -3.

$$1\left(8-2\left(-3-2\right)\left(-1-2\right)\right)$$

Subtract 2 from -3 to get -5.

$$1\left(8-2\left(-5\right)\left(-1-2\right)\right)$$

Multiply 2 and -5 to get -10.

$$1\left(8-\left(-10\left(-1-2\right)\right)\right)$$

Subtract 2 from -1 to get -3.

$$1\left(8-\left(-10\left(-3\right)\right)\right)$$

Multiply -10 and -3 to get 30.

$$1\left(8-30\right)$$

Subtract 30 from 8 to get -22.

$$1\left(-22\right)$$

Multiply 1 and -22 to get -22.

$$-22$$
