]]>In this series of blogs, we bring to you ten topics that are of immediate and intermediate interest for Matrix Algebra.
Here is the second topic where we talk about vectors, binary operations on vectors, set up the concept of linear combination and linear independence of vector. Learn how vectors are used to set up simultaneous linear equations. Get all the resources in form of textbook content, lecture videos, multiple choice test, problem set, and PowerPoint presentation.

Many university STEM major programs have reduced the credit hours for a course in Matrix Algebra or have simply dropped the course from their curriculum. The content of Matrix Algebra in many cases is taught just in time where needed. This approach can leave a student with many conceptual holes in the required knowledge of matrix algebra.
In this series of blogs, we bring to you ten topics that are of immediate and intermediate interest for Matrix Algebra.
Here is the third topic where we talk about binary operations of matrices – subtraction, addition, and multiplication. Linear combination of matrices and rules of binary operations are discussed. Get all the resources in form of textbook content, lecture videos, multiple choice test, problem set, and PowerPoint presentation.

The clarification brought here is for reporting results from prior NSF support. Read the requirements here — https://www.nsf.gov/pubs/policydocs/pappg18_1/pappg_2.jsp#IIC2diii
“The purpose of this section is to assist reviewers in assessing the quality of prior work conducted with prior or current NSF funding. If any PI or co-PI identified on the proposal has received prior NSF support including:
information on the award is required for each PI and co-PI, regardless of whether the support was directly related to the proposal or not. In cases where the PI or any co-PI has received more than one award (excluding amendments to existing awards), they need only report on the one award that is most closely related to the proposal. Support means salary support, as well as any other funding awarded by NSF, including research, Graduate Research Fellowship, Major Research Instrumentation, conference, equipment, travel, and center awards, etc.”
For a proposal recently submitted, I was working with four Co-PIs — let’s call them B, C, D, and E. I will call myself A.
We had worked on a directly related NSF grant in 2013–16 period for which A was the PI, and B and C were Co-PIs. On talking to a NSF official, writing prior-support results description for this grant would only count toward the reporting by one of the three investigators, A, B, or C. So let’s consider it to be counted toward Co-PI B. If PI A or Co-PI C have had other NSF grants as a PI or Co-PI which are current or have been active within the past five years, you will need to report one each for A and C (you cannot game the system if PI A or Co-PI C does not have another grant to report on, while Co-PI B does; each PI or Co-PI has to write prior support description on one grant each, unless a PI or Co-PI has none to report – for an award with an end date in the past five years or any current funding, including any no-cost extensions).
As per the NSF official, you cannot count the same prior-support description for more than one PI/Co-PI.
I got additional advice from my fellow investigator — if you have an unrelated grant that you need to report under prior support guidelines, do so at the end of the proposal description under the heading of “Other Non-Related Prior NSF-Supported Projects”. Otherwise, it will unnecessarily distract the reviewer.
