Numerical Expressions

Description

This example demonstrates how to convert the statement "Negative nineteen by negative eleven" into a numerical expression. The solution explains that the word "by" is often used to express dimensions and can be used to calculate area. In this case, it translates to multiplication, resulting in the expression -19 * (-11).

Numerical expressions involving multiplication are a fundamental concept in mathematics. This collection of examples helps teach students how to accurately interpret various verbal phrases indicating multiplication and convert them into proper mathematical notation. It's particularly useful for understanding how everyday language can represent mathematical operations.

Exposing students to multiple worked-out examples is crucial for developing a comprehensive understanding of this concept. By seeing different phrasings and contexts, students can recognize patterns and build confidence in translating verbal statements into mathematical expressions. This approach helps them tackle a wider range of problems and reinforces their understanding of multiplication with negative numbers.

Teacher to Student: "Let's examine this example together. We're converting 'Negative nineteen by negative eleven' into a math expression. Notice how the word 'by' is used here to mean multiplication. Can you think of a real-world scenario where we might use 'by' to describe multiplication, perhaps when talking about dimensions or area?"
