O-Level Additional Math

-24 ÷-10 + [-36 - 100 / (-5)]÷ 8

= 2.4 + (-16 ) ÷ 8
= 2.4 - 2
= 0.4

Think you have to work on the division (-24 / -10) first.

The answer 2 is correct if the question is phrased this way

-24 ÷ { -10 + [-36 - 100 ÷ (-5)] ÷ 8 }
= -24 ÷ [-10 + (-16)÷8]
= -24 ÷ (-10 - 2)
= -24 ÷ -12
= 2

The WS's answer is 2. Is it correct?

http://farm5.static.flickr.com/4031/4280891135_19760b7710_o.jpg\">

-24 / -10 + [-36 - 100 / (-5)] / 8
= -24 / -10 + [-16 ] /8

Just wondering, from here on, shouldn't it be the -24/-10 be done first ?
= -24 / -10+ [-16]/8
= 2.4 + [-2]
= 2.4 -2
= 0.4

I need some help here.


I remember during my time doing O Levels, I have a lot of Reference Book, This Reference book that I have, after each chapter has lots questions & model answers are provided at the end of the book. The questions are structured from easy to difficult. All past years papers pertaining to that chapter then followed.

But now, I find all the text books, only have notes. Like that how does the students practice to test their understanding ? Or am I missing something …

Any seniors here can help ?

Thanks

I am not so sure if A.Maths is a must for JC.


My understanding is that students can always take H1 Maths in JC, if they have not taken A.Maths at O-Levels.

However, the student may subsequently be limited in his choices for uni, especially engineering courses.

A Maths is often a must for popular course like Business and Accountancy in NUS and NTU

A Maths is a subject that requires LOTS and LOTS of practice.

Good students are usually given the following options:

a) Double language, double math, triple science and 1 humanities, or

b) Double language, double math, double science and double humanities

Out of all the subjects, the more deterministic subjects are Math and Science. In other words, if you know the subject matters well, you should be able to tell where your standing in O-level is. This is why many students are spending time to excel in the Science and Math concepts so as to guarantee themselves with 4 A's for L1R5 calculation.

As for languages and humanities, they are not as deterministic as Math & Science. At http://singapore.math-chinese-tutor.com, we only hear of stories about students who did well for English/Chinese/Humanities in Prelim but scored only B's at O-level. We hear much less of such story in Science and Math.

For this reason, it is advisable to be diligent in Math and Science. For last 2 years the standard for Math and Science were raised and A1 is not as easy to obtain as before. However, for students taking double-Math, I would say that you are almost guaranteed of A1 for E-Math if you study correctly. You should be able to get A2 for A-Math too if you start doing revision systematically in March/April of your O-level year.

Bounty:

My daughter is not able to take A Math in Sec 3, she was given POA. Infact, she could not meet the required marks by just 2 to 3 points. Is ther any way she can take A Math privately? Would it be recognised in JCs? Please help.

A math is rather important as it opens many doors for your child later in her education journey. My advice for you is to go directly to the Math teacher, math hod and principal (dats the way the school channels work) to appeal for your child to take add math. Your child of course has to demonstrate interest in the subject. I have seen a student who is good in math but poor in sciences and therefore loses the opportunity to do add math. Note that your child's ability is ranked with her cohort. In the end, with appeal, that student was allowed to take add math but not allowed to sit for lessons in school. I happened to tutor that child. It was really an uphill task. Students still need to sit for lessons in school whereas the tutor can come in to strengthen concepts. She was prob offered POA cos her other subjects were not too good?

On the other hand, with add math, your daughter can still take H1 math in JCs or institutes which is a reduced version of H2 math. It's important to assess your child's apptitute. Is she more artsy or more sciency? I hope these insights will help you in making decisions in this important time.
