I was very pleased to see them after a long time. For 2 weeks, we had long vacation, called Diwali. Murnal who is my student looked fine. The long vacation and festivals helped him be refreshed. So, we could restart nicely.
Today, we've started (Chapter10- Identities). I really like this part in Mathmetics. So, I wanted him to have interest. There are many kinds of formulas. We made a concept and tried to solve the problems with 5 formulas.
1) (a+b)² = a² + 2ab + b²
2) (a-b)² = a² - 2ab + b²
3) (a+b)(a-b) = a² - b²
4) (x+a)(x+b) = x² + (a+b)x + ab
5) (a+b+c)² = a² + b² + c² + 2(ab + bc + ac)
And, for adopting these concept. I had to explain another basic concept.
For example,
1) (+)*(+) = (+)
2) (+)*(-) = (-)
3) (-)*(+) = (-) as like 2)
4) (-)*(-) = (+)
Every time, when I explain new concept to him, I let him know the most basic one firstly. I think the base is the most important thing in study, even we could adopt it in life. We could see so many famous, important truths or objects. But, I want to say the base which I think it's the most important thing in life is not limited theoretical, it is the practical! When we have meals and rice, we cannot but think about a drop of farmer. When we are grown-up, we cannot but thank to parents, teacher, and many people who make me be able to be in this position. As like this, I think these boys could live with Thanks.
While we were solving the examples, I asked incomprehensible question of Prashant sir who is a supervisor of today as well as my chemistry teacher. I have a duty which I have to teach him correctly and properly. We were very comfortable and easy to talk and understand each other though we've met after long time. Next time, I would prepare more exercises in relation to the Chapter for him.
*Diwali : Diwali (also spelled Devali in certain regions) or Deepavali, popularly known as the "festival of lights", is an important five-day festival in Hinduism, Jainism, and Sikhism, occurring between mid-October and mid-November. Deepavali is an official holiday in India.
