Solve 20(-1)-(-4)(-3)/2[-12div(-3-3)]

$$\frac { 20 ( - 1 ) - ( - 4 ) ( - 3 ) } { 2 [ - 12 \div ( - 3 - 3 ) ] }$$

Evaluate

$$-8$$

Solution Steps

Multiply 20 and -1 to get -20.

$$\frac{-20-\left(-4\left(-3\right)\right)}{2\times \frac{-12}{-3-3}}$$

Multiply -4 and -3 to get 12.

$$\frac{-20-12}{2\times \frac{-12}{-3-3}}$$

Subtract 12 from -20 to get -32.

$$\frac{-32}{2\times \frac{-12}{-3-3}}$$

Subtract 3 from -3 to get -6.

$$\frac{-32}{2\times \frac{-12}{-6}}$$

Divide -12 by -6 to get 2.

$$\frac{-32}{2\times 2}$$

Multiply 2 and 2 to get 4.

$$\frac{-32}{4}$$

Divide -32 by 4 to get -8.

$$-8$$

Factor

$$-8$$
