I used no more or less parentheses than what Slash wrote and I got my answer.Allen1 wrote:Jon wrote:mhmm. To use an example, I would have interpreted the question 4/1/2 as four divided by one half which is obviously 8 whereas you'd interpret it as four divided by one, then divided by two which is 2. Admittedly technically speaking I suppose your interpretation is the correct one. I think it's probably the / rather than ÷ that threw me since I envisioned it as a towered fraction. Using the example I used earlier:Rand al'Thor wrote:
For Jon,
mull over
x/x/x

x/(x/x)
for a bit.
_4_
1/2
rather than 4÷1÷2
which I think you would agree would be 8 since it suggests the 1/2 should be performed first though for which there is no technical reason that it should be. Thus officially
_4_
1/2
= 2 which is what you did.
If you plug it into your calculator, assuming you used parentheses after every term, you should get Rand's answer.

I know what you mean. I'd have friends come up to me asking for some help and when we're working through the question they always stick to exactly how it's been done in past papers and don't know what to do when there's a trick in the question and the method fails to work instantly. They're so reliant on formulae, rules and what have you, it's incredible. It's completely missing the whole point of maths, and, honestly, the exams don't help either.Allen1 wrote:Math in the United States and maybe even internationally is taught with a completely flawed approach, just a mental regurgitation of formulas rather than a conceptual mastery of the topic material.
Meh, my calculators and Wolfram Alpha all point to one answer:Jon wrote:I used no more or less parentheses than what Slash wrote and I got my answer.Allen1 wrote:Jon wrote:mhmm.
