Verbal Expressions: A Definition

In the realm of mathematics, expressions are powerful tools that help us convey numerical concepts and solve problems. Verbal expressions, in particular, play a crucial role in bridging the gap between words and numbers. Unlike numerical or symbolic expressions that use numbers and mathematical symbols, verbal expressions are written in ordinary language. They describe mathematical ideas and relationships using words, phrases, and sentences.

Example:

"The sum of two numbers is 10" is a verbal expression. It describes the mathematical concept of addition without using any numbers or symbols. This makes verbal expressions accessible to a wider audience, including those who may not be familiar with mathematical notation.

Translating Verbal Expressions into Algebraic Equations and Word Problems

When we talk about math, we often use numbers and symbols to express ideas. But sometimes, we find it easier to use words to describe mathematical concepts. These are called verbal expressions.

To solve problems using verbal expressions, we need to translate them into algebraic equations or word problems. This can be a bit tricky at first, but with practice, it becomes easier.

Step 1: Identify the Key Words

The first step is to identify the key words in the verbal expression. These words will tell you what operation to use.

  • Addition: "plus," "sum," "increased by," "more than"
  • Subtraction: "minus," "difference," "decreased by," "less than"
  • Multiplication: "times," "product of," "multiplied by"
  • Division: "divided by," "quotient of," "divided into"

Step 2: Write the Algebraic Expression

Once you have identified the key words, you can write the algebraic expression. Use variables to represent the unknown values.

Step 3: Translate into a Word Problem

If the verbal expression is in the form of a word problem, you can translate it into an equation by following the steps above. Make sure to include all the information from the problem.

Example:

Verbal expression: "The sum of two numbers is 10."

Algebraic expression: x + y = 10

Word problem: Two numbers add up to 10. What are the numbers?

Firstly, verbal expressions simplify problem-solving by providing a straightforward bridge between real-world scenarios and algebraic equations. By translating verbal descriptions into mathematical terms, we eliminate the hassle of complex numerical calculations and unravel problems with greater ease. Imagine a situation where you want to find the total cost of purchasing multiple items. A verbal expression like "The total cost is the sum of the individual item prices" paints a clear picture of the problem, allowing you to effortlessly translate it into an algebraic equation: Total Cost = Price of Item 1 + Price of Item 2 + ....

Furthermore, verbal expressions enhance comprehension by providing a verbal context to mathematical concepts. They help us grasp the underlying logic and relationships between variables. By describing the operations and values involved in an equation, verbal expressions make the problem-solving process more intuitive and comprehensible. For instance, a verbal expression like "The difference between two numbers is six" clearly states the operation (difference) and the value (six), making it easier to visualize the problem and arrive at the solution.

Finally, verbal expressions facilitate effective communication between individuals with varying mathematical backgrounds. They bridge the gap by providing a shared language that is accessible to both experts and non-experts alike. Whether it's conveying mathematical ideas to students, explaining problem-solving approaches to colleagues, or communicating research findings to a broader audience, verbal expressions serve as a powerful tool for disseminating knowledge and fostering understanding.

In essence, verbal expressions are not merely linguistic representations of mathematical concepts; they are a gateway to simplified problem-solving, enhanced comprehension, and effective communication. By harnessing the power of words, we unlock the potential for greater mathematical literacy and empower ourselves to tackle complex problems with confidence.

Consider the following verbal expression: "The length of a rectangle is 5 centimeters more than its width." To find the area of the rectangle, we need to translate this expression into an algebraic equation.

  • Let's represent the width of the rectangle as **x **centimeters.
  • According to the verbal expression, the length is 5 centimeters more than the width, so it can be expressed as x + 5 centimeters.
  • The area of a rectangle is given by length multiplied by width, so we can form the equation:
Area = (length) x (width)

=> Area = (x + 5) x x

By solving this equation, we can determine the area of the rectangle for any given value of x.

Verbal expressions are a powerful tool that connects the world of words to the world of mathematics.
