Real numbers can be divided into rational and irrational numbers, or algebraic and transcendental numbers. The real number set is usually represented by the black letter R., which represents the N-dimensional real number space. Real numbers are uncountable. Real number is the core research object of real number theory.
Question 2: Mathematics, what does real number mean? Real numbers include rational numbers and irrational numbers. Among them, irrational number is infinite acyclic decimal, and rational number includes integer and fraction. Mathematically, real numbers are intuitively defined as numbers corresponding to points on the number axis. Originally, real numbers were just numbers, but later the concept of imaginary numbers was introduced. The original number is called "real number"-it means "real number" (any real number can be represented on the number axis). Mathematically, real numbers are intuitively defined as numbers corresponding to points on the number axis.
Question 3: What does real number mean? Decimal? Hello, I'm glad to answer your question \ (o)/~ I wish you success in your studies.
Real numbers can be divided into rational numbers and irrational numbers. Rational numbers can be divided into integers and fractions, and integers can be divided into positive integers, zero and negative integers. Scores can be divided into positive scores and negative scores. Irrational numbers can be divided into positive irrational numbers and negative irrational numbers.
Decimal is a special form of real numbers, and all fractions can be expressed as decimals. The point in the decimal is called the decimal point, which is the dividing line between the integer part and the decimal part of a decimal.
