What are those 2 pre-fix and post-fix notations and what would a syntax tree look like? I have a hard time seeing why you would ever not read this LtR. Being uneducated I'm curious. | ||

QFT I don't get why would someone consider this as a math question. | ||

I'll try again, I'am not a great conveyer of concept in english, sorry. 2*2 is actually saying 2/1 * 2/1 and if we look at it from here we see that 2/1 is one unity. Reading the left or the right of the /( a or b) on their own is not not an actual number we can do anything with. 5*6/3 should be read as 5*(6/3) resolve the division first since we have both * and / present. because 5*6 is not correct soon as we have the division sign we must take into account what is on the other side of the / sign, above our divisor 3. 5*6/3 Looking at our 6 as freestanding and easy to mulitply with the 5, when it is actually part of a whole unit that is the division of 6/3 the 6 or the 3 are not separate entities; On their own they do not tell us anything only read as the unit they make up (6/3)=2. 5 6 --- * ---- 1 3 And so: If we have "6/3(5)" multiplying the 3 with the 5 first is incorrect since our "3" is not actually representing the number 3, our 3 is the divisor part of a divison unity, its not representing anything on its own. Any divison is most easily read by adding parenthesis 6/3 <-this is one divison unit =>(6/3)=>2 =>2(5) =>10 Edit: Yes, its quite possible its a badly defined question. But when I translate it to paper, it stands clear to me. http://en.wikipedia.org/wiki/÷ In written form a÷b and a/b have the same meaning to me. | ||

Dont confuse the ÷ with the / its different kinda (with the '/' it would be (48/2) x (9+3). | ||

I was confused in the start because ÷ is used for subtraction in Denmark, and / is used for division. My point is, while the rules for solving this problem are quite well defined, the rules that people are taught aren't and differ a lot from school to school or country to country. | ||

48 / (2*9)+(2*3) = 48 / (18+6) = 48 / 24 = 2 48/2*(9+3)= 24*(9+3)= (24*9)+(24*3)= 288 Lets restate the problem 48 over 1 "divided by" 2(9+3) over 1 (easy as pie, flip the second and multiply!) 48 over 1 "multiplied by" 1 over 2(9+3) which gives 48 "divided by" 24. (punch that into a calculator I dare you) Why would you evaluate the bracket last? If I'm wrong I don't know how I got through 4 years of engineering.... This is the thingy I learned in grade 6... you will shit. EBODMASIO Exponents, Brackets, Of, Division, Multiplication, Addition, Subtraction, In Order. the guy was a crackpot. (brackets are first) | ||

My mind ='s blown right now. Really? ÷ would mean to subtract and not - ? That sounds like the biggest bullshit, but what do I know.. I'm not from Denmark. The signs are supposed to be universal, so there would be little confusion. ._. | ||

I have never in my, umm, 20'ish years of education seen ÷ used for division. Ever. | ||

288 [(1781)57%] and 2 [(1354)43%] contradicts with the result of the third poll 1/(2*x) [(1415)68%] and (1/2)*x [(672)32%] | ||
