Math: right answer

[rene_tagle]

eto visit nyo medyo may pagka-elementary ang dating pero malinaw ang pagka-explain regarding PEMDAS

http://www.mathsisfun.com/operation-order-pemdas.html

meron nga pala dun sa bandang baba, order of operation calculator subukan nyo isolve yung pesteng equation na to.

[peejay_07]

ayus tong thread na to ah...

ako answer ko is 2...

i take 2 as the coefficient of (9+3). so distribute muna 2 to (9+3)...

nagpagulo kasi yung pagkakasulat...hehe

[chua_riwap]

OB sa'n ka na......what's your answer?

[roninblade]

OB sa'n ka na......what's your answer?

just keep repeating his name. say it enough times and he'll appear

[chua_riwap]

just keep repeating his name. say it enough times and he'll appear

he's posting in the other threads. i wonder if he bothered checking this thread........

di ko rin mahintay sagot ni OB


PEMDAS RULE

P = (9+3)

E = none

M = 2(12)

D = 48/24

A = none

S = none

RESULT = 2

MDAS RULE

M = 2(9+3)

D = 48/24

A = none

S = none

RESULT = 2



and also quoted from here

Summary

There are five arithmetic operators: ^, *, /, +, and -.
Exponentiation (^) is at the highest level of precedence, multiplication (*) and division (/) are at a lower level of precedence, and addition (+) and subtraction (-) are at an even lower level of precedence.
In the absence of parentheses, operators at a higher level of precedence are performed before operators at a lower level of precedence.
In the absence of parentheses, multiplication and division are performed from left to right, as are addition and subtraction.
Parentheses can be used to explicitly control the order of evaluation of an expression.

PEMDAS RULE

P = (9+3)
E = N.A
M & D = 48 / 2 (12) left to right
A & S = N.A

RESULT = 288

fixed that for you ;)

[ydreph962]

with this equation, x = 48/2(9+3)

2(9+3) should be solved first. you cannot separate 2 from (9+3) because it is considered as one entity. afaik those expressions with parenthesis should be simplified first. kahit na ganong kahaba ang equation basta the first step is to simplify the equation by solving first those expressions inside the parenthesis..

then solve for 48/24 = 2.

therefore my answer is 2..

aren't you reading what you're posting? you're taking one thing that suits your answer and disregarding the rest. only the operation in the parentheses is given precedence. it does not include anything outside.

with the source you posted to get "2" the equation should be - 48 / ( 2 (9 + 3) )

with your parentheses explanation (since you only highlighted that line) your post should be

P = 2(9+3)
E = none
M = none
D = 48/24
A = none
S = none

Marami palang Mathematicians sa tsikot....

Math is an exact science.

Also, Math is the queen of all sciences.

Kapag ganitong klase ang usapan (parang pampulutan sa inuman),- lito na ang lahat ng sciences.... :hysterical:

Paano nagkaroon ng sagot na "42" ???

kaya pala 2 lagi nakukuha mo sir talagang inuuna mo ang multiplication kaysa division, pantay lang ang priority nila, ang rule po is from left to right and not right to left. inuna mo 2(9+3), dapat nauna ang 48/2.

That's the ultimate answer to the ultimate question. hehehe!

wala ako mahanap sa net na may ganyang rule sa math, na yung 2 cannot be seperate from (9+3) because it is considered as one entity. stick to the rule of PEMDAS hindi ka malilito.

That's the ultimate answer to the ultimate question. hehehe!

just dont ask for the ultimate question... IIRC, none yet.

The answer 42 has been provided to you by Deep Thought.

Ah! A reference to Hitchhiker's Guide to the Galaxy. :thumbup:

Quick! We need the Infinite Improbability Drive to scour the universe for the answer

what had happened to "math is an exact science.". . .

if this expression's answer will depend on people's opinions, then it is an invalid one
