Is omitting multiplication sign stronger than another multiplication/division i'd say no. However maybe it is because of an algebraic convention If it was: 48/2n would u say 24/n? or 24n? 24n if you actually wrote 48/2n left to right in a line in a maths exam, it would be treated as 24n and you would lose marks if you meant 24/n, unless you wrote the expression as 48 ---- 2n | ||

48 ---------- 2 So when I see 48/2*12, it looks to me like the 2*12 is under the line. | ||

48 ------- 2(9+3) so first we make 2*9 + 2*3 = 18+6 = 24 then 48 / 24 = 2 thanks... this is right wtv people say so wtv im engineer ;( | ||

48 ------ 2(12) rather than the way it is written, which most American math students see little of; they jump straight into computing and writing problems as fractions. Another failure of our shitty education system  | ||

1. 48 / 2 * (3 + 9) = 288, unambiguously. 2. 48 / 2(3+9) should probably be read as inline notation for 48 over 2 * (3+9), hence 2. If this is not clear from context, seek clarification. 3. 48 DivisionSymbol 2(3+9). Mathematical writing style indicates a good chance that the author is confused, or trying to confuse. Seek clarification. Explanation of #3: division symbols are not really used outside of high school and elementary school classrooms. Also, if an expression refers to a calculation to be performed, then good style would indicate that all operators should be written out explicitly, as in #1. If an expression refers to the result of a calculation, then it should be simplified as much as possible, and can then be written as an inline fraction as in #2. An example where an inline fraction would be appropriate is if the result of a calculation involves indeterminates, such as 48 / 2(x+y). | ||

i read through that thread, absolutely certain that it reached over 60 pages solely because of trolls but there are definitely people who seriously think its 2 (read hilariously stupid posts by frank112) | ||

Still dont get how so many people come up with two, actually took me some time to see why. 150 trolls? Maybe this has to do with how you are taught to read equations in school. | ||
