Today, I have studied Chapter 2 in the book A Core Cause, it talk about some Algebraic topics, and I see A-level is very different to high school program in Viet Nam . In Viet Nam, Everything is complicated and in A-level, essence is the most important.
Example: We have a question:
Solve the equation:
1/(x-1)=2
- In A-level, we only need to write:
1/(x-1)=2 => x-1=1/2. therefore x=3/2
- But in Viet Nam. we have to write the condition x # 2, , if not, we can't get maximum point.
Word Form Today,
Using ......., ....... may be replaced by ....
Substituting .......... for .... in ..... we get

Bye. I feel asleep :)
