This is not disputable. Even ask your PhD friend about that. the 1 is there whether you write it or not. Anyone who knows math knows this. Therefore a/a is always 1, and a/1a is always 1. Therefore a/2a MUST be 1/2, and 6/2a is 3/a, and a = 2+1 so 6/2(2+1) = 3/(2+1). The identity law is something we all can read, and accept. For me, that was deal breaker, along with fractional coefficients written with a '/' all use ( ) as well. |

Anonymous Coward 32057798 And yes, I understand your point with the identity property as well... I also suppose I thought the identity property is normally written out as a fraction, not with a solidus. Nevertheless I don't even think that matters now... a solidus or an obelus imply a fraction... |

Anonymous Coward User ID: 32057798 Canada 01/17/2013 11:25 PM Report Abusive Post Report Copyright Violation | I understand, but the original equation was written with an obelus, NOT a solidus... Quoting: Anonymous Coward 31557420 But the identity law doesn't change, and is used the same way. a ÷ a = 1 (There is still a 1 in front of both a's) 1a ÷ 1a = 1 (not 1*a÷1*a) therefore, 6 ÷ 2n = 3/n PS: The obelus can be interchanged with a divisional slash, but not as a Solidus. Check this out, forgot I had it: =================================== Obelus: The obelus is primarily used as a symbol for division Quoting: Slash: Used between numbers slash means division, and in this sense the symbol may be read aloud as "over". Solidus: The solidus <snip due to html coding of symbols> or a shilling mark is a punctuation mark used to indicate fractions.Now, the obelus and slash can be used interchangeably as long as the slash is interpreted as division NOT mistaken for a solidus. In that regard 6÷2n = 6/2n, which MEANS 6/(2n). Let n = 2+1. caper_26 |

Anonymous Astrophysicist User ID: 1242316 United States 01/17/2013 11:44 PM Report Abusive Post Report Copyright Violation | The solution to the orignal question is easy and straighforward using basic rules established for solving such equations. When numbers are enclosed in parenthesis, this is the mathematical equivelevnt of saying the operation the the parentheseis must first be solved bfor one can continue. The result , since it is in parenthesis, must be multiplied by whatever modifier comes before or after it. using these basic rules the equation is solved as follows: 6/2(1+2)=X 6/2(3)=X 3(3)=9 X=9 Anyone who argues against this being the correct answer is simply an idiot. This is 5th or 6th grade stuff. |

Anonymous Astrophysicist User ID: 1242316 United States 01/17/2013 11:54 PM Report Abusive Post Report Copyright Violation | [link to www.basic-mathematics.com] Quoting: Copy and paste it into this math solver webpage. See what the computer tells you the answer is. 6÷2(1+2)=y You could sub all of these for variables: 6÷2*(1+2)=y You always do bracket first (that IS the rules). Thus it becomes: 6÷2*(3)=y 6÷2*3=y I think we can all agree on that. OK............. Now let's sub these with some variables: 6÷2*3=y n will now mean 3: 6÷2*n=y Which becomes: 6÷2n=y Let's rearrange to put all variable on one side. 6=2ny Now let's solve for ny 6÷2=ny 3=ny Now let's swap n back with a 3. 3=3y Now let's solve for y. 3=3y 3÷3=y 1=y I still get my same answer (because I followed the proper math-rules).

That's the bottom line of all. Or are you thinking parentheses are there just for stupid design purpose thing or something? .
