Step 2: If the number of digits are the same, we start by comparing the highest place values.The real numbers include all the measuring numbers. The symbol for the real numbers is [latex]\mathbb{R}[/latex]. Real numbers are often represented using decimal numbers. Like integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers.The Real Number Line is like a geometric line. A point is chosen on the line to be the "origin". Points to the right are positive, and points to the left are negative. A distance is chosen to be "1", then whole numbers are marked off: {1,2,3,...}, and also in the negative direction: {...,−3,−2,−1}Save. Real numbers are values that can be expressed as an infinite decimal expansion. Real numbers include integers, natural numbers, and others we will talk about in the coming sections. Examples of real numbers are ¼, pi, 0.2, and 5. Real numbers can be represented classically as a long infinite line that covers negative and positive numbers.A natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. This concept of "size" relies on maps between sets, such that two sets have the same size, exactly if there exists a bijection between them.The set of complex numbers is represented by the Latin capital letter C. The symbol is often presented with a double-struck font face just as with other number sets. The set of complex numbers extends the real numbers.What is the symbol "R" in math?
