In mathematics, a real number is a value that represents a quantity along a continuous line. The adjective real in this context was introduced in the 17th century by Descartes, who distinguished between real and imaginary roots of 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 (3.14159265…, a transcendental number). Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced. Any real number can be determined by a possibly infinite decimal representation, such as that of 8.632, where each consecutive digit is measured in units one tenth the size of the previous one. The real line can be thought of as a part of the complex plane, and complex numbers include real numbers.

In this video, we talk about: *Solving Equations in the real number system by factoring. Remember to first find the GCF (if possible) and then use any method to factor: AM, AC, Grouping, DOTS. NOTE: On problem #3, I switched my numbers :( but it worked when I fixed it on the spot :) ... Hope you can still find this video helpful. Stay tuned for more!!
Hope you guys liked this video. It was more of a comedic video so don't take it seriously. Instagram: @Cameron_is_me_ Twitter: @cameronGilbert_

This lecture introduces some painful realities which cast a long shadow over the foundations of modern analysis. We study the problem of trying to define real numbers via infinite decimals from an algorithmic/constructive/computational point of view. There are many advantages of trying to do this: historically this was the point of view towards decimals like sqrt(2) or pi or e, and this provides us with tools to define and evaluate infinite series, functions and integrals. However in reality the idea bumps against seemingly unsurmountable technical obstacles: the difficulties in defining algorithms and implementing arithmetical operations at this level, non-uniqueness of algorithms and corresponding ambiguity in recognizing equality of real numbers, and a vagueness or tautological asp...
