Mathematics is a language for thinking because equations represent compact relationships between quantities. It helps scientists reason through situations and understand systems, rather than just being a calculation tool for finding numerical values.
Science is reliable because it is open to being corrected by new evidence. No theory is ever final; ideas are constantly tested, revised or discarded based on critical examination and updated empirical observations.
A law describes a regular pattern in nature. A theory provides an explanation for why those patterns occur based on evidence. Principles are broad ideas that help make sense of a given situation.
Estimation is vital because it builds intuition, helps detect potential errors in calculations and confirms if a result is reasonable. It allows for quick evaluation, which is often sufficient in early scientific reasoning stages.
