JamesVII Ok. well If I know the variables value then there is no need for the variable to be in there because I can simply replace it with it's value. So your equations look like this. 6/2(1*1+2*1) At this point Pemdas is applied at the answer is discover through simple arithmetic. Without knowledge of the values of your variable then the distributive property is applied. so: 6/2(1a+2a) Well one the parentheses can be simplified to 3a squared. Then you can do 6/2*3a squared or 3*3a squared. You know there's to many buttons in the world, and they're just begging to be pushed. |

JamesVII Well technically you could do it that way, but the problem is you are isolating the 2 when, in fact, the 6÷2 is a whole unite that needs to be distributed. Technically distributive property can be used in basic arithmetic but there is not point since you are dealing with whole numbers at their simplest form and can be solved with out the use of that property. So yes you are right, but you are applying it wrong. 6÷2 is what is directly adjacent to the parentheses and therefore is what needs to be distributed and therefore making you way of being taught still valid.

You are isolating the 2, but that's not possible. For instance when using the distributive property when it would be most useful would be in polynomial and binomial equations. They have variables. 4x(x+xy) as we all know 4x= 4*x but you don't isolate the x and then distribute it by it's self like this: 4(x squared + x squared*y) you always keep the 4 and the x together. this also applies to division. so 4/x(x+xy) = 4/x squared + 4/x squared *y) that is how it has always been done. Check any distributive property article explaining it function and application. you can not isolate the 2. the 2 in this instants it equivalent to and is acting as the x in any binomial or polynomial equation. In which the x is never separated when distributed unless it is explicitly alone. Don't believe me check his links: [link to i47.tinypic.com] ref: [link to go.hrw.com] The 9ers somewhat understand the order of operations, but it is the algebra that is killing them in the end caper_26 Notice the x is not be distributed alone, it's not being isolated in the way everyone seems to be isolating the 2 in this instance, it's numerical partner is coming along for the ride. Why would this rule suddenly be dropped in this equation? The 6 has to be distributed along with the 2. So the when done correctly it looks like such: 6÷2*1+6÷2*2=9 |

Then: The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here:[2] exponents and roots multiplication and division addition and subtraction This means that if a mathematical expression is preceded by one operator and followed by another, the operator higher on the list should be applied first. Mnemonics (like PEDMAS) may be misleading ...especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. |
