More complicated word problem help?

In summary, the conversation discusses the challenges of solving word problems involving equations and how to identify and use relevant formulas to solve them. The speaker also asks for specific examples and clarification on the type of math being studied. The expert suggests breaking down the problem into variables and using relationships to develop a solution in symbolic form.

I've gotten ok at reading and understanding simple word problems, but when there are equations involved, what clues do I look for if I'm not told beforehand what I'm dealing with?

Are these problems with equations involved only in symbolic form? Follow the instructions for the set of exercises so you know what you are expected to do, or what to solve.

EDIT: Involving equations instead of managing a word problem is simpler, and less effort because you already have your equation in symbolic form and then just need to solve it; a word problem requires you to both translate into symbolic form AND then to solve.

Well, what I would like to know is, let's say that I'm sure that the word problem is asking for forumla X, however, I don't know formula X, is there a way I can work out how to correctly put the numbers? I hope that makes sense.

Often enough YES. In some cases, you need to know a set of formulas and use reading comprehension to help choose the related formulas for the problem. In other cases, you may need to know a few formulas by training and instinct, and must DERIVE an equation from which you must DERIVE the needed formula.

Do you have a couple of examples?

Like, let's say you have a problem, where it asks about you starting off with an amount of money, and it grows such and such percent over the year, how much would you have afterwords, with nothing in the way of the typical arithmetic clues to guide you. I know how to do the percent of something, not grow by a percentage. The only other one I can think of at present has to do with a license plate problem, 3 letters, 2 numbers, and how many possible combinations are there? Again, nothing that I recognize from the basic arithmatic, I know I could just count the second, but that'd take forever, and I know that there is probably something simple I could do to figure out maybe, but what that is I have no clue.

Tyrion101,

Regarding post #5:

Those are general descriptions. Do you have a couple of examples?

Are you studying Pre-Algebra, Algebra 1, or Algebra 2? Which, if any?
 
  • #7
Actually, your first description can be treated as something to translate into a form using variables. Assign a variable to everything. What formulas or relationships are found in the problem description? Write these using numbers or variables. What number are you looking to solve for? Develop the answer purely in symbolic form (formula which will be expressed as numbers, some of them being variables.)
 

FAQ: More complicated word problem help?

1. How do I approach solving a more complicated word problem?

When faced with a more complicated word problem, it is important to break it down into smaller, more manageable parts. Start by identifying the given information and what you are being asked to find. Then, try to make connections between the given information and the unknown quantity. Finally, use appropriate equations or strategies to solve for the unknown.

2. What are some strategies for solving more complicated word problems?

There are many different strategies that can be used to solve more complicated word problems. Some common ones include drawing diagrams or models, creating equations or systems of equations, using trial and error, and working backwards. It is important to experiment with different strategies and choose the one that works best for a particular problem.

3. How can I check my work when solving more complicated word problems?

To check your work, you can go back and re-read the problem to make sure you have answered the question correctly. You can also plug your solution back into the original problem to see if it makes sense. Additionally, you can ask someone else to review your work or use an online calculator or equation solver to verify your answer.

4. What are some common mistakes to avoid when solving more complicated word problems?

Some common mistakes to avoid when solving more complicated word problems include misinterpreting the given information, using incorrect equations or formulas, and making calculation errors. It is important to read the problem carefully and double check all equations and calculations to prevent these errors.

5. How can I improve my skills for solving more complicated word problems?

Practice is key to improving your skills for solving more complicated word problems. You can also seek out additional resources such as textbooks, online tutorials, or extra practice problems. Working with a study group or seeking help from a tutor can also be beneficial. It is important to not get discouraged and to keep challenging yourself with new and more difficult problems.
