Variable Expressions

Description

This example demonstrates how to convert a verbal statement into a variable expression using multiplication and addition. The statement "The sum of negative eight and eighteen times more than a number" is translated into the algebraic expression -8 + 18x. This example helps students understand how to interpret mathematical language and represent it symbolically, especially when dealing with negative numbers and phrases like "times more than."

Variable expressions are fundamental in algebra, allowing students to translate real-world situations into mathematical language. This collection of examples reinforces these concepts by presenting various scenarios where variable expressions can be effectively used, helping students develop their algebraic thinking skills.

Exposure to multiple worked-out examples is crucial for students to fully grasp mathematical concepts. Each example provides a unique perspective, reinforcing the underlying principles and ensuring a comprehensive understanding of variable expressions in different contexts.

Teacher Script: "As we examine this example, notice how the phrase 'eighteen times more than a number' translates to 18x. The word 'sum' indicates addition, so we add this to -8. Remember, when we see 'negative eight,' we write it as -8 in our expression. Pay attention to the order of terms in the final expression. Understanding these verbal cues and their mathematical representations is essential for accurately translating word problems into algebraic expressions."
