the algebraic identities which help to solve the factorization problems are: (a+b)(a-b) = a 2 –b 2 (x+a)(x+b) = x 2 + x(a+b) + ab. q6 is every equation an identity? the answer is no. not every equation is considered as an identity. but we can say, every identity is...

Effective applications of these congruences is limited by answers to the following questions: (i) under which conditions, is α ( V ) > 1 ? and (ii) does there exist an equivariant map with the degree easy to calculate? In the present paper, we address both questions. We show that α...
Formulas are like magical spells in the world of mathematics. Just as spells help wizards and witches perform wonders, formulas help us find answers to various mathematical problems. But unlike spells, formulas are not mysterious or secretive but based on logic and reasoning. This article focuses ...
According to Pershan [25], “The Algebra by Example” materials guide students through three stages: analysing solutions, explaining why they work, and applying them to new problems. The analysis stage involves careful reading of solutions to engage with new mathematical ideas; the second stage ...
Projection of a tuple t to some coarser domain y links the answers to a question with the answers to a coarser question. If π y ( t ) = π y ( s ) , then s and t belong to the same answer to the coarser question. As we have seen, the atoms of an atomic labeled ...

Not every question about limits is concerned with the consequence of a variable growing large without bound. The student of calculus will very soon encounter problems in which a variable approaches zero. A typical question asks what happens to the quotient x+h−xh as h gets closer and closer...
