In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers.Every point of a number line is assumed to correspond to a real number, and every real number to a point.. The integers are often shown as specially-marked points evenly spaced on the line.Another way to represent an infinite number is 1/x, when x → 0. The most interesting thing about infinity is – ∞ < x < ∞, which is the mathematical shorthand for the negative infinity which is less than any real number and the positive infinity which is greater than the real number. Here, “x” represents the real number. SymbolSolution. -82.91 is rational. The number is rational, because it is a terminating decimal.

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.

Rational Numbers. Rational Numbers are numbers that can be expressed as the fraction p/q of two integers, a numerator p, and a non-zero denominator q such as 2/7. For example, 25 can be written as 25/1, so it’s a rational number. Some more examples of rational numbers are 22/7, 3/2, -11/13, -13/17, etc. As rational numbers cannot be listed in ...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). Depending on local conventions, zero may be ...

Imaginary number. An imaginary number is a real number multiplied by the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1] [2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. By definition, zero is considered to be both real and imaginary.In mathematics, a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object.A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set..
