In this tutorial, we will be setting up equations for each problem.You will translate them just like we did in Tutorial 2: Algebraic Expressions and Tutorial 5: Properties of Real Numbers. This is where you solve the equation you came up with in your 'devise a plan' step.Whenever you are working with a percent problem, you need to make sure you write your percent in decimal form.
A lot of numeric types of word problems revolve around translating English statements into mathematical ones.
If you need a review on these translations, you can go back to Tutorial 2: Algebraic Expressions and/or Tutorial 5: Properties of Real Numbers.
Many problems are multistep and require some type of systematic approach.
There are a couple of things you need to do when solving problems.
Contrary to that belief, it can be a learned trade.
Even the best athletes and musicians had some coaching along the way and lots of practice.For example, 32% in decimal form is .32 When you are wanting to find the percentage of some number, remember that ‘of ’ represents multiplication - so you would multiply the percent (in decimal form) times the number you are taking the percent of.Math works just like anything else, if you want to get good at it, then you need to practice it.That's what it also takes to be good at problem solving.George Polya, known as the father of modern problem solving, did extensive studies and wrote numerous mathematical papers and three books about problem solving.You may be familiar with the expression 'don't look back'.In problem solving it is good to look back (check and interpret)..Ask yourself exactly what type of information is being asked for: Is it one of addition, subtraction, multiplication, or division?Then determine all the information that is being given to you in the question.I'm going to show you his method of problem solving to help step you through these problems.As mentioned above, I use Polya’s four steps to problem solving to show students how to solve word problems.
