Solve 2^-1-(-2)^-1/(frac{1{2})^-1}

$$\frac { 2 ^ { - 1 } - ( - 2 ) ^ { - 1 } } { ( \frac { 1 } { 2 } ) ^ { - 1 } }$$

Evaluate

$$\frac{1}{2}=0.5$$

Solution Steps

Calculate 2 to the power of -1 and get \frac{1}{2}.

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

Calculate -2 to the power of -1 and get -\frac{1}{2}.

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

The opposite of -\frac{1}{2} is \frac{1}{2}.

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

Add \frac{1}{2} and \frac{1}{2} to get 1.

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

Calculate \frac{1}{2} to the power of -1 and get 2.

$$\frac{1}{2}$$

Factor

$$\frac{1}{2} = 0.5$$
