    True. Remember the SOH CAH TOA thingy we had to memorise (which I did to this day BTW)? What good has it done me, if at all? As for what you learned that helps you now, mostly.... Gee.....I'll probably have to come out with a thesis.

    Speaking of easy, do you know how to use an abacus? I've figured out addition and subtraction but no idea how to do multiplication and division...

    In early 60s, I was helping out in a relative's sundry shop after school & there was an abacus.

    Yep, I was quite fast with it.

    Talking about abacus, here is something I learnt recently.

    My HK friends both husby & wife started a Tuition School 3 years back.

    They use specialist teachers from various schools both Government & Private who like to teach part time.

    ALL subjects that are taught in schools from Year 7 to Year 12 are covered.

    This Tuition School pays about AUD$70 per hour to the specialist tuition teacher and students pay about AUD$40 per hour to this school.

    Imagine, a Math Tuition Class of say 10 students, that's AUD$400 vs AUD$70

    So my friends are laughing to the banks.

    That's beside the point.

    What I wanted to say is this.

    With Maths, my friend said modern kids do not think anymore.

    They only think of calculators, calculators, calculators & calculators.

    For example, one big girl I came across working in Mc Donald had to use a calculator to add up $4 + $3.85

    So they introduce Abacus & these students of all background started to think.

    It works wonder

    It just make them THINK & use their grey matter.

    It seems like they can't think if they were not trained in abacus

    Wonder who designed the HK school syllabus ??

    Admirable. I'm still very slow at it. Having trouble differentiating the denominations.

    Totally agree with you. Abacus force you to think.

    For me, it is English The bē-4ac with a square root thingy hasn't really helped me at all!
    ............................................

    You'd be surprised how Maths has helped us, even without our knowing. Firstly, it has helped us organize our thoughts, sharpened our sense of logic, etc. The skills of connectivity (e.g. bē-4ac to trigo to motion etc) help the brain to understand patterns, identify common building blocks, to solve 'situations/problems'.

    A friend says it reminds him of playing mahjong...move this term here, convert that expression there, to get a 'pong'!...quite like poetry in equations/inequalities. Something like seeing a thing/problem from different angles and the picture becomes much clearer. Once the mind is mapped for this response, the reflex can get transferred to other areas in life...

    Can't agree more. .

    Among the different subjects like algebra, trigonometr, calculus, matrice, geometry, statistic, etc etc.. which is/are your favourites.. ?

    I hate the bloody exam q that asked me to

    1) calculate how long it will take to fill a bath tub measuring 4.5' x 2.1'X 6.9' with the leaky tap dripping water at 1milli lit per 2.3 sec...

    OR

    2) 5 girls travelling in a train at 75mph to a destination 266miles away, carried 2 gross apples and 1.5gross oranges. 2 girls each ate 1 apple every 25min, 3 girls ate at 19min/apple.After a pause of 33mins, 3 girls ate 1.5 orange every 17.5min, 1 girl 27mins and the other girl went to the toilet for 12mins... How many miles would the train have covered when they finished eating all the bananas?

    Gimme me John Dryden, or Coleridge or Wordsworth anytime...and i shalt pen a love prose to weep thee a river flow.

    ...
    ..
    My Answer 1) Too bloody long innit!
    2) By george! I Donno, I was still in the toilet with the other lass.

    Why hate this question, this is a kiddy stuff..

    Time taken = Volume of bath tub / leaky tap flow rate

    Volume = a x b x c x [m] .... [m] is conversion factor from feet to cm

    Volume = am x bm x cm = abcm3

    Flow rate = 1 / 2.3 = 0.43 ml/sec (cm3/sec)

    So, the blardy time to fill the bath tub = 4.5 x 2.1 x 6.9 x (12 x 2.54)3 / 0.43

    = 4.29 x 106 second
    = 0.07 x 106 minutes

    or just simply 1.93 x 103 hours....

    They were eating blardy apples and oranges all the while .... since when they ate bananas ??

    Or they changed their mind while you were in toilet ???
