Word problems can be some of the most difficult types of questions on any test. They will test your problem solving abilities, as you must figure out what the question is asking. When you first attempt a word problem, write all numbers and quantities to the side of the word problem, since it will be easier to manage the information when it is not surrounded by text. Also, see if there is any unnecessary information that you can eliminate from the problem. You can then begin solving the problem.
Words That Mean Addition:
For Example - The coat cost the store $55 and its price was increased by $30 so that the store could make a profit.
Words That Mean Subtraction:
For Example - In a store‐wide sale, all $55 jackets are reduced by 35% and $30 shoes are reduced by 45%.
Words That Mean Multiplication:
For Example - The store sold 20 jackets in a sale at $35 each. The store sold 30 hats at twice their original price of $10.
Words That Mean Division:
For Example - The school divided equally among its students 350 bags of candy.
Words That Mean Equals:
For Example - What does each jacket sell for when the store has a 33% discount on winter-wear?
Once you have read the word problem and translated key words to their operations, you must quickly decide what information is important. Make sure to write out formulas, underline content, and visually organize the information in written form.
You may also see questions which give an equation and ask you to determine which description best matches it. For example:
To solve this problem, you should think about what math operations you would use to solve each part. For A, you would use subtraction; for B, you would use division; for C, you would use addition; and for D, you would likely use subtraction and addition. Thus, B is most likely to be correct, since 60 quarters divided amongst 5 people equals 12. This matches the equation above.
