What have i learnt in chaptper 2.1 ?
In chapter 2.1 , what i have learnt is basically about expanding algebraic expression . It is smiliar to what i've learnt in Secondary 1 . But this yr , i understand more about it .
What are the difficulties ?
- I will get confused easily by the negative & positives signs .
- I get confused when there are too many numbers to multiply .
- I don't know where to start from when there are too many brackets .
What I want to know more ?
I want to know how to expand algebraic expression in a shorter & faster method . Because i often take up a lot of time on solving one question as i have to do check each sign by each sign slowly just in case i use the wrong signs .
gald u able to understand better this year. take note of the -ve sign, this will be common mistakes by most students. there is no short cut to such topics. practice more will help u do better. =D
