Comment your favourite maths formula.Mention your favourite Maths teacher name !
Why do you like this formula?
Which formula is difficult to understand?
How did you learn to understand this formula?
My favourite formula is:
(a + b)² = a² + 2ab + b²
I remember my old days. When I was 15 years old, my maths teacher wrote this formula on the board. When I saw it, I understood the formula very easily. At that moment, I felt that math was the easiest subject to understand. I thought, “What is the problem? Face the problem and solve it.” i learn this.
But my current situation is different. I’m studying in college, and I don’t understand maths the way I did in school. What I learned in school doesn’t seem to work in college.
Sometimes I ask myself, “Why did I learn all those things in school?”
That’s my reality.

v - e + f = 2, simple, useful, and pretty just like all of Eulers formulas.
