reaalväärtustena

Reaalväärtustena, meaning "real values" in Estonian, refers to the set of all real numbers. The real numbers encompass all rational numbers (numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero) and irrational numbers (numbers that cannot be expressed as a simple fraction, such as pi or the square root of 2). The set of real numbers is denoted by the symbol R.

Real numbers can be visualized on a number line, where each point on the line corresponds to a unique real number. This set includes positive and negative numbers, as well as zero. The properties of real numbers are fundamental to many areas of mathematics, including algebra, calculus, and analysis. Operations such as addition, subtraction, multiplication, and division are defined for real numbers, following specific axioms and rules. The concept of ordering is also crucial, allowing for comparisons between any two real numbers. Understanding reaalväärtustena is essential for comprehending a vast range of mathematical concepts and applications in science and engineering.
