If A/B is the same as

A
B

then

A/B is not the same as A÷B as you stated earlier

Because

A x B ÷ C is the same as B ÷ C x A because B ÷ C x A is not the same as B ÷ (C x A)

100 ÷ 10 x 5 is 50, not 2

48 ÷ 2 x 12 = 288 = 48 ÷ 2 x (9+3) = 288

Another trick question! Celullite is hereditary.

"Cellulite is hereditary, so much so that the indications of who will get it, and to what degree, are present almost from birth," says dermatologist Amy Newburger, MD, director of Dermatology Consultants of Westchester in Scarsdale, N.Y. In fact, Newburger tells WebMD, skin biopsies taken from infants are highly predictive of whether cellulite will develop later in life, based on the number of septa bands found in the skin.

The answer is 42 and I have proof!



Quote:
42 (forty-two) is the natural number following 41 and preceding 43. The number has received considerable attention in popular culture because of its appearance in The Hitchhiker's Guide to the Galaxy, as the "Answer to the Ultimate Question of Life, the Universe, and Everything".

I don't know why there is any discussion on this.
I did the math. Came up with 288. Voted right after the thread started.

I see how the answer 2 could be calculated if it was a different equation than posted.

but i've been told by many expert sources that it's 69...

What's to argue about? Can it be explained any more clearly than this?

Google the equation and it simplifies the equation by rendering it this way:

(48 ÷ 2) * (9 + 3) = 288

But that's not right as it added the parens.... ...and they are the key.

trekkor 04-11-2011 02:30 PM
That is how you solve the equation as written in the original post, however.

I still say its Z-MANS attempt to keep us out of the chest thread.,...............

rattlsnak 04-11-2011 03:13 PM
no matter which way you initially thought it was, after reading all the 'rules' and 'orders', how can anyone still think it's 2?

That's it right there. The wrong way and the right way.

People who work with numbers accept the convention that everything to the right of the division sign is the denominator. I never learned it as a "rule" it's just the way things are done in the technical world. If this equation was in a problem on an engineering exam and you got 288, you would fail the test. If you were designing an actuator for an airplane wing, the plane would crash.
I don't remember the third grade. Maybe if you were in the 3rd grade, you'd pass.

You're joking, right? ;)

Two different equations, two different solutions, - both are right...right?

Right! :)

What you're saying is that math rules are arbitrary, i.e., "based on or subject to individual judgment or preference"? :eek: Geez, I can't accept that at all! :eek:

If this equation was in a problem on an engineering exam and you got 288, you would fail the test.

I'd certainly contest that! And the competence of the prof. too! And, win or lose, I'd question my choice of engineering school and probably transfer to another school.

If you were designing an actuator for an airplane wing, the plane would crash.

Whoa! :eek: If what you say is true, I suddenly have an intense fear - of - flying phobia!! :eek:

I don't remember the third grade. Maybe if you were in the 3rd grade, you'd pass.

If I could do basic algebra in the 3rd grade I'd probably have graduated high school by age 10. :)

The word 'algebra' was probably gibberish to me at that age. And I'm no dummy! As a matter of fact, my parents were convinced for the longest time that I was going to be an astronaut, based on what my teachers told them when they asked how I was doing at PTA meetings. They told them that I was taking up space.

This expression messes with commutative and associative properties of arithmetic..

What is the answer to this?

12(2x2) divided by 2(9+3)

or

12(2X2)/2(9+3)

or

((2X2)(6X2))/((2+2+5+3)2)

Maybe Mrs Kovner, my 9th grade algebra teacher will rise from the ashes and smack me in the head again..

That picture above looks like the overflow at Lake Berryessa.
