Q: What’s the difference between a PhD in Mathematics and a large pizza?
A: The pizza can feed a family of four. Q: How do you pick-up chicks in a Calculus II class? A: A mathematician walks into a bar Filed under: Upper-division jokes, Walks into a bar — Travis @ A mathematican walks into a bar accompanied by a dog and a cow. The bartender says, “Hey, no animals are allowed in here.” The mathematician replies, “These are very special animals.” “How so?” “They’re knot theorists.” The bartender raises his eyebrows and says, “I’ve met a number of knot theorists who I thought were animals, but never an animal that was a knot theorist.” “Well, I’ll prove it to you. Ask them them anything you like.” So the bartender asks the dog, “Name a knot invariant.” “Arf! Arf!” barks the dog. The bartender scowls and turns to the cow asking, “Name a topological invariant.” “Mu! Mu!” says the cow. At this point the bartender turns to the mathematican and says, “Very funny.” With that, he throws the three out of the bar. Outside, sitting on the curb, the dog turns to the mathematican and asks, “Do you think I should have said the Jones polynomial instead?” |
Two mathematicians walk into a bar
The first one says to the second that the average person knows very little about basic mathematics. The second one disagrees, and claims that most people can cope with a reasonable amount of math. The second mathematician goes off to the washroom, and in his absence the first calls over the waitress. He tells her that in a few minutes, after his friend has returned, he will call her over and ask her a question. All she has to do is answer “‘a‘ squared plus ‘b‘ squared.” She repeats: “A square plus a bee square?” He repeats “a squared plus b squared.” “Ay squared plus bee squared?” “Yes, that’s right”, he says. So she agrees, and goes off mumbling to herself, “Ay squared plus bee squared… Ay squared plus bee squared… Ay squared plus bee squared…” The second guy returns and the first proposes a bet to prove his point, that most people do know something about basic math. He says he will ask the blonde waitress a simple algebra question, and the second happily agrees. The first man calls over the waitress and asks “What is (a+b)2?” The waitress says “Ay squared plus bee squared” and while walking away, turns back and adds with a wink “…assuming a and b are anticommutative.” |

is 1) exponents which are all 1 so do nothing to simplify the expression 2) add inside parenthesis 48÷2(12) 3) multiply & divide from left to right 24(12) => 288 ans 288 |
In the perfect world of mathematics 0.999999... will never be equal to 1
in the world of computers/calculators all numerical results are limited to the memory architecture that is used. All answers that utilize the full array of available numerical memory or more will be rounded or truncated depending on how the instruction set is implemented. |

1. Exponents 2. Stuff inside parentheses 3. Stuff right next to but outside parentheses 4. Multiplication from left to right except the stuff in rule 3 that's stuck to the outside of the parentheses 5. Addition According to him (not me)... 48÷2(12)-->48÷24=2 What I find so surprising is that the ratio in the poll keeps going farther and farther towards the wrong answer. |

to force the x before the ÷ in the above it would have to be in parenthesis 48 ÷ (2(12)) similarly 48 / 2 x 12 is not the same as 48 / (2 x 12) |

4. Multiplication from left to right |
But if you set the 2 in the equation to x and set the equation equal to 288, x then = 1/72. Thus proving 2 is the correct answer.

48÷2(9+3)=288 48÷X(9+3)=288 (9+3)=288/48 or 1/X(9+3)=288/48 X (9+3)=X 6 X=2 Quote:
The best way to write this problem so that everyone should be able to understand it 1 x 48 x (9+3)=288 2 |

It's 288. That's it. KT |
You can go to a site, Algebraic Order of Operations Calculator. According to that, the answer is 288.
You get the division sign by hitting the Alt key and then 2,4,6 simutaniously (the key pad to the right) and release. My initial thinking was that 2 in the equation was a factor or a coefficient and so that side would get resolved first with the result being 2. But this seems to be not the case. It's treated as a multiplier, so it follows that the order is from left to right. |

ok to check 48÷X(9+3)=288 rewrite in rational form http://forums.pelicanparts.com/uploa...1302788114.gif inside parenthesis http://forums.pelicanparts.com/uploa...1302788149.gif multiply numerators & denominators http://forums.pelicanparts.com/uploa...1302788209.gif cross multiply http://forums.pelicanparts.com/uploa...1302788247.gif perform the inverse operation http://forums.pelicanparts.com/uploa...1302788277.gif |
