Trivia 8÷2×(2+2)

Which order of operation were you taught in school?

  • PEMDAS

  • BEDMAS

  • Both


Results are only viewable after voting.
So, ang may bias ay yung procedure na sinusunod mo, enclosed na siya sa imaginary parenthesis kaya hindi pwedeng i-apply yung mga rules.
Paano ba i-apply yung distributive property, 2(2+2) para ma-eliminate yung parenthesis? hindi ba multiplication over addition, 2(2+2) = (4+4) = 8. Hindi yung shortcut 2(2+2) = 2(4). Sabi ko nga, walang conflict ang PEMDAS at BODMAS (BEDMAS), kundi nasa individual na gumagamit ng procedure. Doon ako sa may rules.

Tapusin na natin ito, paps. Alam naman natin na hindi tayo mag-a-agree sa procedure.
I normally would have solved like you do. Took me a whille to let go of my bias. Never thought math could be subject to dogma too..
that is why I shared this post in the first place.

Eto try mo. It might get the point across.

1÷2÷4÷1×8

1÷2÷4÷1×8
1 lods
 
8÷2×(2+2) = x
8÷2×4 = x
8÷8 = x
1 = x

ung sabi mo sa example mo lods, this is just straight up wrong
Yup. Pag nag pemdas ka iba sagot.
may misconception ka ata lods sa pemdas

sa pagkakaalam ko kasi same level of precedence ang multiplication and division and ung standard is to calculate em from left to right

Inexplain ko nga yan sa post paps. Hahah
 
Ang pagkakaintindi ko sa PEMDAS ay equal lang ang order ng paggamit sa operations na (MD) at (AS). Kung alin ang mauuna, in this case, yung division ang nauna bago multiplication kaya yung division ang dapat unahin.
 
basically, to sum (haha math pun) up my thoughts, PEMDAS/BEDMAS are just there for ease of use and para matandaan easily, the only thing that matters is ung order ng operations which is:


1. lahat ng nasa grouping symbols like parenthesis, brackets etc
2. exponents
3. multiplication AND division from LEFT TO RIGHT
4. addition AND subtraction from LEFT TO RIGHT (it matters din po hehe)

not a pemdas/bedmas supporter, they're just acronyms to guide, not strictly follow

anyways lods, nice thread po! naenjoy ko magisip kahit panandalian lang hahaha
 
Good to know na nililinaw na ito ngayon. Sa generation ko as in order ng pemdas talaga ang turo.

Pero dapat simplified na ang equation at ang matitira na lang ay yung mga operation signs (+-x÷), wala na ang P at E at yung iba like /.

I agree dito,

Keep in mind din kung pano isinulat.
Multiplication and division has the same priority. So, in the expression,
8÷2×4 = x​
it should be solved from left to right. Yan ung next logic na dapat sundin. Technically pemdas and bedmas is actually, the same.

Nakikita ko yung sinasabi mo. But you are omitting the × symbol.
You assume kasi na parehas ang implied problem pag sinulat ng ganito

8÷2×(4) or 8÷2(4)​

Magkaiba yan. Kasi jan sa kanan, we really treat this like this:
8÷[2(4)]
pero ung sa kaliwa, there is still a possiblity na Ang intention nung given problem is:
8/2×(4) --> 8/2 treated as a fraction

If aalisin mo ung Multiplication symbol, alisin mo na din ung division symbol.
(⁸/₂)4 = 16 or ⁸/₂(4)=16
 
PEMDAS or BODMAS parehas lang Po.
May rule sa PEMDAS at sa BODMAS na once magkadikit Ang Division and Multiplication and also Addition and subtraction isosolve mo Ang equation from left to right.

PEMDAS itinuro sa Amin noong grade 6 and ever since alam ko Yung rule na 'yan.
