Provide an appropriate response.Are parentheses as important when adding rational expressions as they are when subtracting rational expressions? Why or why not?
What will be an ideal response?
No; when adding, no sign changes are required, so the result is the same regardless of parentheses. When subtracting, however, the sign of each term of the expression being subtracted must be changed, and parentheses are needed to ensure that this is done.
