Variable Expressions

Description

This example demonstrates how to convert a verbal statement into a variable expression using multiplication and addition. The statement "Negative fourteen times a number plus fourteen" is translated into the algebraic expression -14x + 14. This example helps students understand how to interpret mathematical language and represent it symbolically, especially when dealing with negative coefficients and constant terms.

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 'Negative fourteen times a number' becomes -14x. The phrase 'plus fourteen' directly translates to + 14. Pay attention to how the negative sign affects only the variable term, not the constant term. This distinction is important when working with more complex algebraic expressions."
