This channel is a means to reaching out to students, parents, teachers/learners, and professionals with extra support to grow and improve their mathematics skills. Being part of this platform, students will be able to complete their assignments, compete anywhere, and take their learning to the next level. This channel is where we make mathematics fun by paying attention to basics, details, adopting different methods, and ensuring that we build a solid foundation that will result to better achievements.
This channel will be resourceful and will cover topics of the following subject areas: Geometry, Algebra I & II, Trigonometry, Precalculus, college/university preparation, and praxis (math content areas).
I have a BS and MS in mathematics and have been a teacher for over 20 years. I am an active high school teacher with passion for teaching mathematics, many years of experience educating children and adults from elementary through college levels. Subscribe to enable me show you how.

A 3 Reducing Rational Expressions
มุมมอง 492 หลายเดือนก่อน
This video will show you how to factor the terms of a given rational expression in order to reduce the expression to its simplest form. In this video, you will learn how to factor trinomials, the difference of two square and the difference of two cubes.
A.3 Finding Domains of Algebraic Expressions
มุมมอง 422 หลายเดือนก่อน
This video addresses examples of finding domains of algebraic expressions. It shows you how to write domains algebraically, using set-builder, interval notations or using inequality symbols.
P.6 Finding Complex Roots of Quadratic Equations
มุมมอง 562 หลายเดือนก่อน
In this video, I will show you examples of finding complex roots of quadratic equations. Since some quadratic expressions are prime and we cannot factor the trinomials, we will use the quadratic formula or completing the square methods to find the complex roots of the associated quadratic equations.

8TH PERIOD STAND UP🗣🗣🗣
Hey Mr. Samuel. Can you make a video about range, domain, and codomain. I was still a little confused in the test
Thanks Yazsin. This is not intentional. The denominator has to remain x(x-2)(x+2).... Thanks for noticing this.
Cool! But I’m a little confused on #3. On the third to last step, the denominator changed x(x+2)(x-2) and (x+2)(x-2). Was this intentional?
Great video! At 3:19, when you said 2 times 2, did you mean 2 divided by 2?
Yes, I meant to say 2 divided by 2. It's great to have you on this platform Yazsin.
