Final answer:
The claim that every number's absolute value is the same as the number itself is false, as the absolute value of a negative number is positive. This concept is a fundamental aspect of mathematics that requires understanding rather than memorization.
So option (B) is the correct answer.
Step-by-step explanation:
I disagree with Ricardo's claim that every number's absolute value is always the number itself. The absolute value of a number is defined as its distance from zero on a number line, regardless of direction. Therefore, while the absolute value of a positive number is the number itself, the absolute value of a negative number is its positive counterpart. For example, the absolute value of -5 is 5, not -5. It's critical to understand this concept as it is fundamental in mathematics and is used across various topics, from solving absolute value equations to understanding complex numbers.
When students deeply understand the logic behind mathematical concepts rather than just memorizing rules, they are able to apply these concepts more effectively in real-world scenarios and complex problem-solving. This understanding is essential in fostering a solid mathematical foundation.
