Probably the greatest source of error, though, is the use of variables without definitions.
When you pick a letter to stand for something, write down explicitly what that latter is meant to stand for.
(And, if you can't think of any meaningful definition, then maybe you need to slow down and think a little more about what's going on in the word problem.) In all cases, don't be shy about using your "real world" knowledge.
Sometimes you'll not feel sure of your translation of the English into a mathematical expression or equation. For instance, if you're not sure if you should be dividing or multiplying, try the process each way with regular numbers. But figuring out the actual equation can seem nearly impossible. Be advised, however: To learn "how to do" word problems, you will need to practice, practice, practice.The first step to effectively translating and solving word problems is to read the problem entirely.You'll also be expected to know that "perimeter" indicates the length around the outside of a flat shape such as a rectangle (so you'll probably be adding lengths) and that "area" indicates the size of the insides of the flat shape (so you'll probably be multiplying length by width, or applying some other formula).And "volume" is the insides of a three-dimensional shape, such as a cube or sphere (so you'll probably be multiplying).In July, the hobby store sold a total of 20,777 trading cards.How many more trading cards did the hobby store sell in July compared with a normal month?Pick variables to stand for the unknows, clearly labelling these variables with what they stand for. You need to do this for two reasons: " stands for, so you have to do the whole problem over again.I did this on a calculus test — thank heavens it was a short test! (Technically, the "greater than" construction, in "Addition", is also backwards in the math from the English.You'll be expected to know that a "dozen" is twelve; you may be expected to know that a "score" is twenty.You'll be expected to know the number of days in a year, the number of hours in a day, and other basic units of measure.
