What happens to the determinant when we perform a row operation

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

0:50 if n is large, then somewhere there's an ak47

||conclusion of this video||
If, to any row (or any column), any constant times another row (or column) is
added, the value of the determinant remains unchanged.
row j = row j - row i ===>> not change det(A) note: The order affects!

3:44 How? How is the determinant of B equal to the determinant of the sum of the 2 matrices?

[zeeeeeezeeeeee]

How about if it was addition ?? ri + (c)rj ??

THank you

just because you're too slow to get it that doesnt make it a bad video

Not up to your normal stellar standards.. You made your example matrices too big for a start.

dammn...i wish you were my uncle...i would b the next Khan lol
