There are some problems that prove difficult to a lot of students to understand. Students struggle with seeing the math behind the words. When your child reads the problem aloud, they are saying and hearing the problem.
And they are even, so they could be 2 and 4, or 4 and 6, etc.
We will call the smaller integer n, and so the larger integer must be n 2 And we are told the product (what we get after multiplying) is 168, so we know: n(n 2) = 168 We are being asked for the integers Solve: That is a Quadratic Equation, and there are many ways to solve it.
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.
Below is a math problem solver that lets you input a wide variety of math problems and it will provide the final answer for free. The version below will show you the final answer only.
You'll see a button "View steps" and this takes you to the developer's site where you can purchase the full version of the solver (where you can see the steps).
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.
— and, trust me, you don't want to do this to yourself! Certain words indicate certain mathematica operations. But the order in addition doesn't matter, so it's okay to add backwards, because the result will be the same either way.) Also note that order is important in the "quotient/ratio of" and "difference between/of" constructions.
If a problems says "the ratio of Some times, you'll be expected to bring your "real world" knowledge to an exercise.
