See a solution process below:

First, rewrite the expression as:

$1/2 - 2$

We can now put the term on the right over a common denominator by multiplying by the appropriate form of $1$ :

$1/2 - (2/2 xx 2) =>$

$1/2 - 4/2$

We can now subtract the numerators over the common denominator:

$(1 - 4)/2 =>$

$-3/2$

How do you evaluate \frac{1}{2}+(-2)\frac{1}{2}+(-2)?
