Answer 1

Answer:

• 1.In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line. 
• 2.The Egyptian mathematician Abū Kāmil Shujā ibn Aslam (c. 850–930) was the first to accept irrational numbers as solutions to quadratic equations or as coefficients in an equation, often in the form of square roots, cube roots and fourth roots.
• 3.The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary rootsof polynomials. The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as √2 (1.41421356..., the square root of 2, an irrational algebraic number). Included within the irrationals are the transcendental numbers, such as π
• 4.In addition to measuring distance, real numbers canbe used to measure quantities such as time, mass, energy, velocity, and many more. Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding tointegers are equally spaced.
• 5.“A set of values used to represent different quantities is known asNumber System“. For example, a number systemcan be used to represent the number of students in a class or number of viewers watching a certain TV program etc. The digital computer represents all kinds of data and information in binary numbers.
