It's both 288 and 2 >.<


Why is it that when everything is working fine the least possible thing fails...


You should be able to solve this. 

You're platinum mad.


I could blue, if I could read it.




if integral f(x) dx from 1 to 4 is 6 then what is the value of integral f(5x)dx from 1 to 4




The problem is stated ambiguously.
The answer is either 288 or 2. Were it stated explicitly as either (48/2)*(9+3) or 48/(2*(9+3)) it becomes immediately clear which answer is correct. The lack of an explicit statement of the multiplication implies that it is grouped with the evaluation of the term in brackets, however without further clarification it is impossible to reduce the problem to a single solution. 



You sir, get a star badge. Weldone.

I thought a/2 is the same as a * 0.5, but I dont know if it is really defined that way, and I don´t care enough to look it up. In a more general case it should always be the multiplcation with the inverse element, therefore I am a bit sure of it.
@blue_banana Your english version does not coincide with the japanese one? The japanese one should be solvable with Fermats little theorem I guess. 



This was taken from Dr.Math himself....hes a doctor...of MATH.
http://mathforum.org/library/drmath/view/54341.html This paragraph makes it very clear. "I don't know of a general rule among mathematicians that implied multiplication should be done before explicit multiplication. As far as I'm concerned, all multiplications fit in the same place in the order of operations. It's not an unreasonable rule, though, since it does seem that implied multiplication ties the operands together more tightly, at least visually; but the idea of Order of Operations (or precedence, as it is called in the computer world) is supposed to be to ensure that everyone will interpret an otherwise ambiguous expression the same way  so if some texts change the rules, or if people do what feels natural, the purpose has been lost."

You basically have to do the paranthesis first, clearing them out gives you the 2(12) then after you do the multiplication to get rid of it which gives you your 24, then we get to the division which makes it 48/24=2

The japanese one should be solvable with Fermats little theorem I guess. Well done good sir, have another! and in English... Any integer divided by 14 will have a remainder between 0 and 13. Given a is has remainder of 6 and b has remainder of 1 when divided by 14, what is the remainder of x when divided by 14, given x is an integer solution to x^22ax+b=0?

Calm thee shit down people! I take this, thee answer is . . WHO CARES?


well umm..


I prefer the answer 288 (refer to the large paragraph from my last post), though the answer is actually undefined.

Add in parentheses, then divide, and then multiply.
