What i enjoyed most about these chapters?
I dont really like this chapters as they are quite complicating and its very easy to make careless mistakes. But this particular chapter 2.7 was quite easy. I need to use the cross method for this chapter.
What i think i did well in this chapter?
I like chapter 2.7 as ,i had already stated, quite easy as the cross method is easy.
What i found difficult or confusing:
The most confusing thing is to memorise all the formulas and to know when is the right time to use it, especially in exams where i will not know which formula to use on which question.
What i can do to improve:
As i said, the most difficult thing is to know when is the right time to use that particular formula. To solve this very important problem, i shall do more practices when i have time.

What i have learned in chapter 2.1 and the difficulties
What have i learned in chapter 2.1:
I have learned that, for e.g.:
a(x+y)=ax+ay
a(x-y+z)=ax-ay+az
The main thing is to multiply an algebraic expression by a single term. We can also extend it to find the product of two algebraic expressions such as (a+b)(x+y).
What are the difficulties?
I have difficulties solving the advanced questions such as: (2p-q)(2p+3q)-(p+q)(p-5q)
because i usually make careless mistakes and only 1 careless mistake will make the whole answer that i gave wrong.
What do i want to find out more?
I would like to know how to avoid making careless mistakes so that i will not get the question wrong and so get more marks for any examinations and tests that have questions that is linked to chapter 2.1 .

Mathematics Project
At 1st, my group went to the court to measure the perimeter of it using Isaac's measuring tape, but the measuring tape is not long enough so we shared measuring tapes with Karlina's group.
Actual length:14.3
breath:6.1
After that, we rounded the numbers of to make calculations easier
Length:14m
Breath:6m
we used 14mx6m to get 84cm^2
