Solve =-1/2+1+1/2-1

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

Evaluate

$$0$$

Solution Steps

Convert 1 to fraction \frac{2}{2}.

$$-\frac{1}{2}+\frac{2}{2}+\frac{1}{2}-1$$

Since -\frac{1}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.

$$\frac{-1+2}{2}+\frac{1}{2}-1$$

Add -1 and 2 to get 1.

$$\frac{1}{2}+\frac{1}{2}-1$$

Since \frac{1}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$\frac{1+1}{2}-1$$

Add 1 and 1 to get 2.

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

Divide 2 by 2 to get 1.

$$1-1$$

Subtract 1 from 1 to get 0.

$$0$$

Factor

$$0$$
