Solve (-10-2*4):(-2-1)+(-6):(-3)-(-1)

$$( - 10 - 2 \cdot 4 ) : ( - 2 - 1 ) + ( - 6 ) : ( - 3 ) - ( - 1 )$$

Evaluate

$$9$$

Solution Steps

Multiply 2 and 4 to get 8.

$$\frac{-10-8}{-2-1}+\frac{-6}{-3}-\left(-1\right)$$

Subtract 8 from -10 to get -18.

$$\frac{-18}{-2-1}+\frac{-6}{-3}-\left(-1\right)$$

Subtract 1 from -2 to get -3.

$$\frac{-18}{-3}+\frac{-6}{-3}-\left(-1\right)$$

Divide -18 by -3 to get 6.

$$6+\frac{-6}{-3}-\left(-1\right)$$

Divide -6 by -3 to get 2.

$$6+2-\left(-1\right)$$

Add 6 and 2 to get 8.

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

The opposite of -1 is 1.

$$8+1$$

Add 8 and 1 to get 9.

$$9$$

Factor

$$3^{2}$$
