<span>When we remove those parentheses, the sign of every term
within the parentheses changes.</span>

Problem 2.   Remove the parentheses.

a)   p + (q −r + s) <span>= p + q − r + s</span>

b)   p − (q −r + s) <span>= p − q + r − s</span>

In each of the following problems, remove the parentheses, then simplify
by adding the numbers.

For example,

<span><span><span>(x − 3) − (y − 4)</span>  =  <span>x − 3 − y + 4</span></span> <span>   =  <span>x − y + 1.</span></span></span>

The sign preceding  (x − 3)  is understood to be + . Therefore the signs within those parentheses do not change.

But the sign preceding (y − 4) is minus.  Therefore, y changes to −y, and −4 changes to +4.

Finally, it is the style in algebra to to write the literal terms, x − y, to the left of the numerical term.
