Sophie Germain Indentity

this expression is always a composite number and the identity of its factorization is called Sophie-Germaine identity.
this is of significant importance in Number Theory, especially in Fermat's last theorem.

A teacher starts with an introductory lecture over the concept and few basic problems. Then a difficult multistep problem is posed to the students. The students then try to solve that problem in single or groups. Moreover this or similar problem the students have not tried earlier. 
Teacher moves among groups trying to check what they have done and often suggest them hints. Later each group member comes to the board and solves his/her solution.

Amazing right!

Ideas connecting Algebra and Geometry

I used to think, that Descartes coordinate geometry was the first to see algebra and geometry are same. But then came across another instance where numbers and geometry came together in what is called as polygonal numbers
Which elaborated, seems like sequence of numbers seen as pebbles laid onto floor for each element of the sequence.
Interesting hmm!
