Difficulties with real numbers as infinite decimals ( I) | Real numbers + limits Math Foundations 91
There are three quite different approaches to the idea of a real number as an infinite decimal. In this lecture we look carefully at the first and most popular idea: that an infinite decimal can be defined in terms of an infinite sequence of digits appearing to the right of a decimal point

Critical Numbers of f(x) = 1/x
In this video we find the critical numbers, if any, of the function f(x) = 1/x. Recall that critical numbers are numbers in the domain of the function where the derivative is zero or undefined. Great Calculus Book: https://amzn.to/3VfotAU This is my affiliate link. As an Amazon Associate

Visit http://ilectureonline.com for more math and science lectures! In this video I will explain and give an example of what is the principle of a rational expression. We can only simplify a rational expression if we can factor the same factor from both the numerator and the denominator.

Geometric Algebra, First Course, Episode 03: Relative Magnitudes and Scalars.
We grow our Vector to be a Scalar + Vector as we examine how to divide a geometric quantity by another. We see that it is OK to divide quantities that have the same aspect ("direction") even though we don't know how to calculate absolute magnitudes.

Algebra 1 2.09d - Rules for Division
Further discussion of rules for division. This video discusses dividing zero by a number, dividing a number by zero (not allowed!), and also the fact that division is not commutative and is not associative. Examples are included. From chapter 2 of the Algebra 1 course by Derek Owens.
