What is quantitative reasoning?

Quantitative reasoning (QR), also known as quantitative literacy, is the ability to understand and use numbers and data in everyday life. It involves applying mathematical and statistical concepts to solve real-world problems and make informed decisions. Unlike abstract mathematics, QR focuses on the practical application of mathematical skills in various contexts.

Key components of quantitative reasoning include:

• Number Sense and Operations: Understanding the meaning of numbers, their relationships, and how to perform basic arithmetic operations.
