Don't immediately jump in and solve the problem, instead look at it for a second and think about what it is asking you, what does it want you to figure out. Verbalize the problem, this will allow you to catch any semantic mistakes that you might be making. After you have said the problem out loud, separate the problem into at least two parts. Look at the parts in your head, and try to accomplish the desired goal. Say three plus five equals eight.
Clarity is the most important thing in mathematics.
Word problems exist in all realms of mathematics. They are often people's nemesis. Make it a numerical problem. First, as above, observe the problem. Now, once again, verbalize the problem.
