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).

You, sir, are the best teacher I’ve ever known in my life. You made maths the most interesting subject for me. I really can’t express my gratitude in words for your amazing teaching!! I never knew integration could be so easy! You are the reason why I excel at all my tests.

Thank you very much for these videos sir …
