Solve 1/1-(-1)*(-2)=(-1)+(-2)/1-(-1)*(-2)=

$$\frac { 1 } { 1 - ( - 1 ) \cdot ( - 2 ) } = \frac { ( - 1 ) + ( - 2 ) } { 1 - ( - 1 ) \cdot ( - 2 ) } =$$

Solution Steps

Multiply -1 and -2 to get 2.

$$\frac{1}{1-2}=\frac{-1-2}{1-\left(-\left(-2\right)\right)}$$

Subtract 2 from 1 to get -1.

$$\frac{1}{-1}=\frac{-1-2}{1-\left(-\left(-2\right)\right)}$$

Divide 1 by -1 to get -1.

$$-1=\frac{-1-2}{1-\left(-\left(-2\right)\right)}$$

Subtract 2 from -1 to get -3.

$$-1=\frac{-3}{1-\left(-\left(-2\right)\right)}$$

Multiply -1 and -2 to get 2.

$$-1=\frac{-3}{1-2}$$

Subtract 2 from 1 to get -1.

$$-1=\frac{-3}{-1}$$

Fraction \frac{-3}{-1} can be simplified to 3 by removing the negative sign from both the numerator and the denominator.

$$-1=3$$

Compare -1 and 3.
