Introduction

In mathematics, the ability to choose the right sentence to express a problem is a crucial skill that can make a significant difference in solving it. A well-crafted mathematical sentence can help identify the key elements of the problem, make it easier to understand, and provide a clear direction for solving it. In this article, we will explore how to choose the mathematical sentence that most accurately expresses the information in a problem and would be most helpful in solving it.

Understanding the Problem

Let's consider the following problem:

"In a certain city, there are 17 television stations. Six of the stations are broadcast below channel 20. How many television stations are broadcast above channel 20?"

Choosing the Right Mathematical Sentence

To choose the right mathematical sentence, we need to identify the key elements of the problem and express them in a clear and concise manner. In this case, the problem involves two key elements:

The total number of television stations (17)
The number of stations broadcast below channel 20 (6)

We can express these elements using the following mathematical sentence:

Let's use the following variables:

T = Total number of television stations
B = Number of stations broadcast below channel 20

The mathematical sentence:

T = B + (Number of stations broadcast above channel 20)

Why this sentence is helpful:

This sentence is helpful because it:

Clearly expresses the relationship between the total number of stations and the number of stations broadcast below channel 20
Identifies the unknown quantity (Number of stations broadcast above channel 20) that we need to find
Provides a clear direction for solving the problem (by finding the difference between the total number of stations and the number of stations broadcast below channel 20)

Alternative Mathematical Sentences

While the sentence we chose is helpful, there are other ways to express the problem using different mathematical sentences. For example:

T - B = Number of stations broadcast above channel 20
B + (Number of stations broadcast above channel 20) = T
Number of stations broadcast above channel 20 = T - B

Why these sentences are not as helpful:

These sentences are not as helpful because they:

Do not clearly express the relationship between the total number of stations and the number of stations broadcast below channel 20
Do not identify the unknown quantity (Number of stations broadcast above channel 20) that we need to find
Do not provide a clear direction for solving the problem

Conclusion

Choosing the right mathematical sentence is a crucial skill that can make a significant difference in solving a problem. By identifying the key elements of the problem and expressing them in a clear and concise manner, we can create a mathematical sentence that is helpful in solving the problem. In this article, we explored how to choose the mathematical sentence that most accurately expresses the information in a problem and would be most helpful in solving it.
