Linear algebra is the first kind of algebra that a student is introduced to.
We recognise linear equations because each term is either a constant or the product of a constant and a variable. Note that there are no squares or other powers, an no xy terms or anything like that. These equations can have one or more variables but we are limited to one variable per term.
Although the study of linear equations is extensive and can enter many dimensions, and can involve complex numbers (for example), I am mostly going to restrict myself to work that would be covered in high school (and the first year or so of college/university).
I’d like to take the chance to thank you for this awesome channel. You achieve what many teachers fail to achieve: You do not beat around the bush and you have the ability to make even complex topics sound simple, which is a gift.
Thank you for helping me with my final examination preparation. Keep up the great work. You deserve a lot more views, that is why I am glad to share your work with other students struggling with maths.
Yours Sincerely from Germany
