_{Mathematicians also play with some special numbers that aren't Real Numbers. The Real Number Line. 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 ... In the same way, sets are defined in Maths for a different pattern of numbers or elements. Such as, sets could be a collection of odd numbers, even numbers, natural numbers, whole numbers, real or complex numbers and all the set of numbers which lies on the number line.

Keep reading to learn what is a whole number, its definition, and its symbol.Whole Numbers This set of numbers is the same as the set of natural (counting) numbers except for the symbol to represent nothing (0). W: 0, 1, 2, 3, 4, 5… The symbol # is known variously in English-speaking regions as the number sign, hash, or pound sign. The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔ .The answers are all real numbers where x < 2 or x > 2. We can use a symbol known as the union, ∪ ,to combine the two sets. In interval notation, we write the solution: ( − ∞, 2) ∪ (2, ∞). In interval form, the domain of f is ( − ∞, 2) ∪ (2, ∞). Exercse 3.3.3. Find the domain of the function: f(x) = 1 + 4x 2x − 1.9. 9 = 3. Table 9.1. The square roots of numbers between 4 and 9 must be between the two consecutive whole numbers 2 and 3, and they are not whole numbers. Based on the pattern in the table above, we could say that 5–√ 5 must be between 2 and 3.

Sign (mathematics) The plus and minus symbols are used to show the sign of a number. In mathematics, the sign of a real number is its property of being either positive, negative, or 0 . In some contexts, it makes sense to consider a signed zero (such as floating-point representations of real numbers within computers).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.A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, b are real numbers and i is an imaginary number. i = √−1 − 1 and no real value satisfies the equation i 2 = -1, therefore, I is called the imaginary number.Rate this symbol: 3.0 / 5 votes.

We use a line drawn over the repeating block of numbers instead of writing the group multiple times.A real number is any number that is the coordinate of a point on the real number line. Real numbers whose graphs are to the right of 0 are called positive real numbers, or more simply, positive numbers. Real numbers whose graphs appear to the left of 0 are called negative real numbers, or more simply, negative numbers. A real number is a rational or irrational number, and is a number which can be expressed using decimal expansion. When people say "number", they usually mean "real number". The official symbol for real numbers is a bold R, or a blackboard bold . Some real numbers are called positive. A positive number is "bigger than zero ".
