real

**Real** – In mathematics, “real” most commonly refers to the set of real numbers (ℝ), which includes all rational numbers (fractions) and all irrational numbers (non‑repeating, non‑terminating decimals). Real numbers can be represented on an infinite continuous number line, allowing for operations such as addition, subtraction, multiplication, division (except by zero), and taking roots. They are used to model continuous quantities in physics, engineering, economics, and everyday measurements. Views Nigeria
