48/2(9+3)

even calculators don't know the answer:



Posting from another forum:

To be clear, let's add a multiplicative symbol in there:

48 / 2 * (9+3)

Parenthesis are first, so this simplifies to:

48 / 2 * 12

Multiplication and division are the same level in the order of ops heirarchy, and they are done from left to right, so it's:

24 * 12 = 288

Agree with most that it could be written more clearly as (48/2)*(9+3).

To clarify... PEMDAS heirarchy specifies 1) parenthesis, 2) exponents, 3) multiplication and division left-to-right, 4) addition and subtraction left-to-right.

Except the answer is 2, not 288.

Lol.

Didn't you all learn the order of operations?

"Please Excuse My Dear Aunt Sally."

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

48/2(9+3) = 48/2(12) = 48/24 = 2

I believe that was 5th grade for me, so just before middle school.

I learned the order of operations in 3rd grade. Parenthesis means you process everything inside the parenthesis. The 2 is clearly outside the parenthesis.

Okay, let's do order of operations.

Brackets
Exponents
Division/Multiplication
Addition/Subtraction

48 / 2 * (9+3)
48 / 2 * 12
24 * 12
288

We're done here.

Lol.

I learned it in 3rd grade too.

Why even put 48/2, silly geese.

So, is 2/2pi = 2/2*pi ?

My calculator says no.

So, is 2/2pi = 2/2*pi ?

My calculator says no.

It's pi.
2/2*pi
1*pi
pi

It's pi.
2/2*pi
1*pi
pi

They are not the same thing, you can't interconvert them. 2/2pi is not the same as 2/2*pi.


Guys, if any of you got a real calculator in which you can write a whole expression before hitting "=", I invite you to write these two expressions on your calculators and come tell me what they say:
48/2(9+3) and 48/2*(9+3)

Mine gives 2 and 288, respectively.
That "2" in front of the parenthesis works as a coefficient, therefore the whole expression is considered the denominator of what comes above it, the result is different if there was really a multiplication sign in there.

PS: I'm not sure if people are discussing this seriously or just trolling around since this is the funhouse... I'll stop here.

Weird French calculators...

It' a CASIO fx-92, it's not french.

Too late. All your bases are belong to us now.

Oh shi, not my bases!

We're done here.

Hipster calculator right there.

Hipster calculator right there.

TI-85 is obviously retarded.

B.E.D.M.A.S. Biaches!!! :+)

The problem lies with the person who wrote out the mathematical equation. 48/2(9+3) is 48/2*(9+3), not 48/(2(9+3). ggnorere

B.E.D.M.A.S. Biaches!!! :+)

That has nothing to do with this. This is about notations.

Thread is now about the calculators you have in your house.



My parents use the top one for... something. I don't know what.
The bottom left calculator is my TI-30X IIS, what I use for calculus. The bottom right is my lovely TI-84 Plus, which I used in the entirety of high school (excluding now, when I only use it to check answers).
I used to have a TI-83, but I gave it to a friend because those calculators are friggin' expensive.

I saw it like this.

48
________
2(9+3)
= 2

If it were (48/2)(9+3)

48
__ (9+3)
2
then = 288

It's 288. It would be 2 if it were 48/(2(9+3))
