Solve (-9(2-8+2)-9)+2(-4(-1-5+3)+9)=

$$( - 9 ( 2 - 8 + 2 ) - 9 ) + 2 ( - 4 ( - 1 - 5 + 3 ) + 9 ) =$$

Evaluate

$$69$$

Solution Steps

Subtract 8 from 2 to get -6.

$$-9\left(-6+2\right)-9+2\left(-4\left(-1-5+3\right)+9\right)$$

Add -6 and 2 to get -4.

$$-9\left(-4\right)-9+2\left(-4\left(-1-5+3\right)+9\right)$$

Multiply -9 and -4 to get 36.

$$36-9+2\left(-4\left(-1-5+3\right)+9\right)$$

Subtract 9 from 36 to get 27.

$$27+2\left(-4\left(-1-5+3\right)+9\right)$$

Subtract 5 from -1 to get -6.

$$27+2\left(-4\left(-6+3\right)+9\right)$$

Add -6 and 3 to get -3.

$$27+2\left(-4\left(-3\right)+9\right)$$

Multiply -4 and -3 to get 12.

$$27+2\left(12+9\right)$$

Add 12 and 9 to get 21.

$$27+2\times 21$$

Multiply 2 and 21 to get 42.

$$27+42$$

Add 27 and 42 to get 69.

$$69$$

Factor

$$3\times 23$$
