what say you...(math problem)

Post this in a People's Republic of China Jeep Forum and watch it get solved as 288 in the first reply,
only to be followed by at least 6 pages of "americans can be such tards".
:dunce:

Of course it is

PEMDAS

M comes before D, so yep 2 is the answer. Anyone that doesn't think so is generally a self-righteous a-hole when they answer.

I resemble that remark!
:twak:

 

[srimes]

You don't know how to PEMDAS

...

Multiplication and division(no, M does not come before D, its which ever you encounter first working from left to right

No, I don't know "PEMDAS," I know order of operations (I know this wasn't directed at me). And this whole "which ever you encounter first working from left to right" is BS. Its a false rule! Follow order of operations (or pemdas if you prefer), and process it in any damn order you fell like.

Doing MaD or AaS in any order it is incorrect as well.

Take this part of the solution: 48/2*12

If it was done in any order you could do 2*12 first. However that wouldn't work.

48/24
=2
which is incorrect

If done correctly, left to right you get:
24*12
=288

You did it wrong. You changed the problem when you changed the order that you processed the numbers.

Process the 2 and the 12 first correctly and you get 6. Times 48 = 288.

48/2*12 =
48*12/2 =
12*48/2 =
12/2*48 =
1/2*12*48 =
288

The reason M and D have the same precedence level is that the order that you process them doesn't change the result. Same with + and -.

48 -2 +12 =
48 +12 -2 =
-2 +12 +48=
58

You just said that it didn't matter in what direction you worked the equation. I.e. L to R vs R to L. That is what I did, which according to you should have worked, but it did not.

48/2*12 =
48*12/2 =
12*48/2 =
12/2*48 =
1/2*12*48 =
288

The examples you gave are different from doing the equation in any order.

The reason M and D have the same precedence level is that the order that you process them doesn't change the result.

Yes, M and D have the same precedence however, doing the equation in any order will give you different results.
24*12 will give a different answer from 48/24.

This has been a problem for years. I used to work for HP and helped design desktop calculators. We stated in the manual what the execution order would be. IIRC given the rules HP used the number would have been 2.

 

[Talyn]

Any insight into why HP did it that way? The casio graphic calc i have says 288 as well as Derive.

 

[srimes]

No, no, no. :banghead:

I'm not talking about how you type it in to a calculator. That's a separate issue. I'm talking about the math. How are my example equations not showing that left-right order doesn't matter?

24*12 will give a different answer from 48/24.

? Well I'd hope so...

 

[Talyn]

I am not talk anything about using a calculator concerning the L to R issue. I am talking of working the equation left to right vs. right to left.

Take this part of the solution: 48/2*12

If it was done in any order you could do 2*12 first. However that wouldn't work.

48/24
=2
which is incorrect

If done correctly, left to right you get:
24*12
=288

I'm bust'n ..... I can't believe some people are still voting for "2":roflmao:

Dude why would you bump this... let it die.
