Many students find that adding and subtracting rational expressions can be complicated because there can be numerous steps used to solve an equation. Given all these steps, it’s easy to make mistakes, but there are ways to avoid common mistakes. For example, a student might use line paper so that her steps are clear, while another student may know a trick for checking her answers midway through a problem.
