Transformations, congruence, and similarity.

Negative numbers: multiplication and division.

Negative numbers: addition and subtraction.

Multi-digit multiplication and division.Arithmetic patterns and problem solving.Equivalent fractions and comparing fractions.And they’re even better than traditional math worksheets – more instantaneous, more interactive, and more fun! Just choose your grade level or topic to get access to 100% free practice questions: After watching the video, I found myself easily visualizing linear subspaces and how to relate them to subsets, which makes it mush more easier to explain to my peers who also have difficulty understanding the topic.That’s because Khan Academy has over 100,000 free practice questions. Khan in the video helped me visualize what linear subspaces were, therefore providing me a solid comprehension on the topic. Khan goes in a step-by-step, easy to follow approach, which helps me reorganize my thoughts and understanding of the topic from the very beginning (this is very helpful to ensure I don’t misunderstand anything). I initially found myself ‘quite’ understanding what was going on for this topic, but I felt that it wasn’t solid enough for me to thoroughly explain it in my own words. This video has helped me understand the fundamental concept of linear subspaces, where I had trouble getting the ‘click’/eureka state in class lectures. Basically we are talking about space and direction), hence linear subspaces have additional properties that must be fulfilled such as having the zero vector and being closed under addition and scalar multiplication. The video takes an approach of describing how linear subspaces are quite similar to subsets of Rn, but since we are talking about vectors and spaces (non-science/engineering students may find this hard to understand. The video illustrates what is a linear subspace of a set, Rn (the set of all real numbers, symbolized by the capital ‘R’, in the dimension of ‘n’).

The video above is about a topic in Linear Algebra, which is Linear Subspaces. Today I’d like to share a video that helped me understand a topic that I had difficulty with
