A real number is a number that can be found on the number line, including all positive and negative numbers, fractions, decimals, and irrational numbers such as √2, Ï€, and e.
real numbers are numbers that can be represented on a number line, and can take any value from negative infinity to positive infinity. They can be either rational (able to be expressed as a fraction) or irrational (not able to be expressed as a fraction). Examples of real numbers include integers (whole numbers, such as 1, 2, 3, etc.), fractions (such as 1/2, 3/4, etc.), and irrational numbers (such as the square root of 2 or pi).
A number system is a system of representing numbers, which is used to represent real-world quantities, such as measurements or monetary values, or for counting and ordering objects. The most common number systems are the decimal system and the binary system. The decimal system is based on tens and is used in most parts of the world and is the basis for the metric system; it uses a radix of 10. The binary system is based on powers of two and is mainly used for computer applications; it uses a radix of 2. Other number systems include the octal system (radix 8) and the hexadecimal system (radix 16).
