New self made Mathematics simple questions

We have made some questions based on logics which will help in competitive exams.
The Directorate for Mathematical and Physical Sciences (MPS) at the National Science Foundation (NSF) is now accepting supplemental requests to support one (additional) Ph.D. student per award, as long as the graduate student is a United States Veteran. The proposed MPS-GRSVs will afford Veterans an opportunity to conduct research towards a doctoral degree with an NSF MPS Directorate active grantee.
