In this lesson we'll learn the six step method that you can use to solve word problems. You may have to repeat some steps a few times when working through a problem. However, you'll see how you can translate math problems into equations. You should look for keywords in the problem that will help you determine how the equation should be written. For example, when there's a 'sum' or 'together' mentioned in the problem, it means that you should use addition. Finally, you'll see examples of word problems. Some of these examples involve trigonometry, unknown quantities, and other.
When solving word problems we go through 6 steps to arrive at a solution
Read the problem
Assign a variable to the unknown quantities
Write an equation using the connections in the problem
Solve the equation
State your answer to fit the context of the problem
Check your solution to see if it is reasonable
You may have to repeat some steps a few times when working through a problem.
Look for key words in the problem that will help you determine how the equation should be written.
Always check your solution to see if it is reasonable in the context of the word problem.
