What are Imaginary Numbers?
Imaginary numbers are a fundamental concept in Algebra 2, crucial for solving equations that have no real solutions. This video provides a comprehensive introduction to imaginary numbers, making the topic accessible and easy to understand.
The video starts by explaining the need for imaginary numbers, particularly in situations where the square root of a negative number is encountered. You'll learn that the imaginary unit, denoted as
𝑖
i, is defined as the square root of -1. This definition forms the basis for all operations involving imaginary numbers.
Step-by-step examples illustrate how to perform basic arithmetic operations with imaginary numbers, including addition, subtraction, multiplication, and division.
Visual aids and practical exercises help reinforce the concepts, ensuring you understand how to work with imaginary numbers in various mathematical contexts. The video also addresses common misconceptions and errors, providing tips to avoid these pitfalls.
Ideal for students, teachers, and anyone looking to deepen their understanding of algebra, this video breaks down the concept of imaginary numbers into manageable parts. By the end, you will be confident in using imaginary numbers to solve complex mathematical problems, enhancing your overall algebra proficiency.

Can you please do an episode where you go more into depth about imaginary numbers in more of a higher mathematical sense? This was a topic that always confused me to no end. I just couldn’t figure it out. It got way too abstract and I’m sure I just didn’t have a good professor that could explain it. Plus, this was over 12 years ago, so maybe it was me too. Anyway, I’m willing to take another crack at it.
Talented teacher. Blessings
Big thank you for giu dedication and ease and depth of explanation.i wish I had you as my teacher back then. Keep it up👍
Thanks for your understandable explanations of math and physics topics.
THANK YOU... SIR...!!! It makes sense in the PRAPANCHAM ( stability & instability )...!!! THANKS AGAIN...!!!
Thank you so much sir❤ watching from philippines 🇵🇭 😊
תודה!
Thanks a lot professor I follow you from Algeria.
Great as always
Very nice video
Nice 👍
I think the electrical quantities like a.c source, resistors inductor and capacitors are represented by complex numbers.

Yes, they are.
good...
Please can u make a video about centripetal and centrifugal force calculations.
Make this guy the president of the world.

Lol he’s good for sure. But leave him in his domain. 😂
Roots are where the solution crosses the X axis for a quadratic equation. where are the imaginary roots located on the XY plot ?
They’re like the 4,000+ gods man made up….they’re imaginary!
If they are imaginary---they would not exist. No one would know they are there.
Pliz dont stand infront of the whiteboard 😅😅😅
It proves that math was invented and not discovered.
Really really inreresting! but why do you keep repeating yourself? I'm 10 minutes intgo the viceo (25%) and all i've learnt is that i-squared = -1.
Imaginary numbers is what you see after a bad mescaline trip into the void between realities, where the visible light spectrum curves and fractals into itself.
