Please (Parenthesis)

Excuse (Exponents)

My (Multiplication)

Dear (Division)

Aunt(Addition)

Sally.(Subtraction)

[shizzzon 461]

wow i havent heard that in forever...

But yes, 2 is the answer.

Apparently, the other TI calculator wasn't given proper instructions in it's firmware to know basic rules.

Sad though.. that one is newer

[eggyhustles 33]

I'm going with 288

It can be either or since multiplication and division are in the same rank. The Multiplication/Division and Addition/Subtraction are interchangeable based on which order they appear in the equation.

so

48/2(9+3)

48/2(12)

24(12)

288.

Its 288.

I vote 288! 9+3 = 12.....48/12 = 24 therefore 12x24=288!

2. multiplication comes before division.

[Frostedflakejake 148]

Multiplication and Division are the same step. They should be done in order of left to right after the parenthesis so the correct answer is 288.

I'm surprised the ti-85 said it was 2...

But it's definitely 288. Not only is what i stated correct, but Mathematica, Matlab, and Java all agree with me as well. (just tested)

The answer is 2. I just tried it two different ways on pen and paper.

This is algebra (which I got a 92 average in last year). It's just basic P.E.M.D.A.S.

[steveo50 3]

Yea you have to distribute the 2 to the 9 and 3 then divide 48 by 24 and that makes 2 the answer

[Duran 387]

It's your basic order of operations...The stuff you learned in Pre-Algebra.

[kirill007 52]

lol, seriously?

My nephew which is 9 year old can solve it.

[topgun 262]

What this is here is a poorly written equation.

48÷2(9+3) =288

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

[Gatorfooseball08 2]

I'm Thinking 288, Eggyhustle and Frostedflakejake are right that Multiplication/division are interchangeable, so then priority goes left to right. 48/2*12=288.

[shizzzon 461]

you are wrong because Parenthesis comes before all that...

Seriously like Duran and kirill said..

We should be lucky that these equations are not used in car audio, lol.

[ssh 924]

It's plain bad notation.

[Gatorfooseball08 2]

Correct, so you would add the 9+3 first, but the 2 isn't in the parenthesis, so then it reads 48/2*12=288

[shizzzon 461]

NO... u are doing it WRONG...

Parenthesis inside AND anything strictly attached to it is done FIRST.

9+3 = 12

2(12) (This STILL needs to be simplified before solving...

So = 24..

Now we have 48 / 24 = 2

[Gatorfooseball08 2]

Not according to the guy with a doctorate from MIT in theoretical math and another from GT in Electrical Engineering.... but ok

[topgun 262]

NO... u are doing it WRONG...

Parenthesis inside AND anything strictly attached to it is done FIRST.

9+3 = 12

2(12) (This STILL needs to be simplified before solving...

So = 24..

Now we have 48 / 24 = 2

Where did you learn this?

How about we write it like this

48 ÷ 2 x (9+3)

48÷2 x 12

Multiplication and division are on the same level, therefore you work left to right, you don't do one before the other randomly because you feel like it.

[shizzzon 461]

What this is here is a poorly written equation.

48/2(9+3) =288

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

maybe i am looking at this wrong

[Duran 387]

The answer is 2.

The order of operations is: Parenthesis > Exponents > Multiplication = Division > Addition = Subtraction. IN THAT ORDER.

The equation is: 48/2(9+3)

[Per the order of operations, solve everything in parentheses]

So: 48/2(12)

[Now solve multiplication]

So: 48/24

[Now divide]

2

The 2 next to the (9+3) means you multiply it to the parenthesis. It doesn't mean that it is given a higher power.
