selesaikan dalam kurungan dahulu...

mahu tambahkan dahulu baru darab pon boleh

mahu darab dahulu baru tambah kemudian pon boleh

selepas itu...baru dibahagikan ke pangkal hadapan

jawapanya adalah 2

jadi VC anwar ibrahim...konpem 2 minit je

    aku pernah bertekak ngan lecturer sampai dia fail aku.Bukan kes ini tapi convert decimel dan binary.. Dia guna consept buku dia. kira lain.. aku guna cara aku dapat lain..Next sem,dia ngaku silap kira.. WTF. Aku mintak tukar kelas terus.. Untuk normal people benda ni takde effect sangat.Tapi untuk sesiapa kerja hidup kerja mingira ,consider bahaya.

calculation tuk science bergantung kpd konsep atau pembinaan sesuatu projek, tak semudah tulis2 macam nih, org yg terlibat akan tahula cara mana yg digunakan.

kebarangkalian tuk math problems and solutions can be infinity sometimes, tp disbbkan inilah juga org boleh solve golden problems.

klu applykan math tuk semer mender, nnti abeh jadik cam kite, tak dpt conform ngan majority, smpai bertukar byk courses dr medic ke natural science ke physics ke engineering ntah ke aper lagi nih sbb once kite bajar sesuatu, kite akan terpikir sesuatu yg lain dr teori yg sedia ada n org akn anggap kite giler bila kite bersungguh nk provekan. tgk skrg nih la, even still dlm bidang nuke n high energy physics, thp keboringan kite ber-ubah2, kejap kite kt accelerator beams, kejap kt nuke power, kejap nuke weapon, kejap kat radiation imaging, last2 semer kajian smpai sudah tak siap n makin bertimbun idea. takper la, nnti kite mati leh la sedara mara kite kasik kt mana2 institutions segala mak nenek kajian, teori, algorithm kite yg ader nih. just kesian kt ramai supervisors and advisors yg asek pening ngan kite nih, the worst student & research associate ever.

selesaikan dlm bracket dlu..then baru buat yg darab or bahagi sume2 tuh uols
so..it could be

48/2(12)=48/2*12=24*12= 288

or

48/(2*12)=2

wah..confusing jugaklahh

    Ya la.  for basic math everything must be equal  0 = 0 .. Kalau rumus  kita belajar ,kita just fill in  jer.Tetapi betul tak betul itu isunya.Sebab kita tak faham functionality formula tersebut.

48/2(9+3)

NO 2 tidak berada dlm bracket...
so..i think kna selesaikan dlm kurungan<bahagi<darab

so..jawapannya ialah 288

pakai prinsip PEMDAS pom serupa jugak dapat 2...kena follow keutamaan dia yang mana dulu

48/2(9+3)

(9+3) = (12)
kena setelkan dalam kurungan sampai habis...

lepas tu disusuli dengan darab
2 (12) = 2 X 12 = 24

baru bahagi
48 bahagi 24

= 2

Dah thread sampai 4 aku bagi answer aku dan kenapa
Basic rule of math.Everything is equal
Ah Chong  == Ah Chong
48  /2  (9+3) == Ah Chong
48 / 2             == Ah Chong / (9+3)
24                     == Ah Chong / (12)
24 * 12           == Ah Chong
288                 == Ah Chong.

isu utamanya..
soalannye dh mula2 salah. bakpe pikir jawapan kalu soalan tu bangangkan jawapan2 korang..
mana bole tulis soalan matematik cmtu kt kertas peperiksaan..

kalu tulis stail taip cmtu kt kertas SPM,
mau 99% pelajar failed..

tulisla mana atas, mana bawah,mana tengah..

aiyoo..apa pening2..

byk isu lain lagi penting, oke next..
