In Soviet Russia, 2 distributes you.
:rofl
Because that’s how it works.
It’s NOT THE SAME as having a multiplication sign between them
His could also be written as
48/6(3+1)
I’ll quote this again, as you dont get it
Distributive property of multiplication. Early Algebra.
The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire term and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (29+23). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it.
So this can be rewritten as:
48 / (29 + 23)
Which leaves us with
48 / 24 = 2
Answer = 2.
Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (29+2*3). Be very careful with your signs.
Ill also copy this from math.edu

The distributive property of multiplication over addition is simply this:* it makes no difference whether you add two or more terms together first, and then multiply the results by a factor, or whether you multiply each term alone by the factor first, and then add up the results.
That is,
*** adding up the term first; then multiplying by the factor** =* multiplying each term by the factor first, then adding up the resulting terms
That is:****** Factor(Term1 + Term2 + … + TermN)* =** Factor(Term1) + Factor(Term2) + … + Factor(TermN)
If we call the Factor “a,”* and we call the terms “b”, “c,”…“t”, then this statement begins to look like a mathematical statement:
************************************************* a(b + c + … + t)*** = a(b) + a(c) + … +a(t)
** EXAMPLE:*** (The factor is 3, and the three terms* are 2, 7, -5)
************************************************************ 3(2 + 7 - 5)* =** 3(2) + 3(7) + (3)(-5)
**************************************************************** 3(4) ******* =**** 6*** +* 21*** -* 15
****************************************************************** 12******** =** 12
This is kinda cool, but you might wonder* what possible use it might be.* I mean, really, why wouldn’t you ALWAYS add the terms together first, and avoid all that yukky multiplication?** Well, the answer is:** It comes in very useful when you have terms that cannot be added together first, because they are not like terms.
Case in point:*** 3(2x + 4).*** We can’t combine the 2x and the 4, because the first is x’s and the second is 1’s (four of them).* But, suppose this expression showed up in an equation like:
**************************** 3(2x + 4) = 5
and we were asked to solve for x?* What to do?* We have to get the x’s untied from the 1’s, right?* Using the distributive property of multiplication over addition is what is going to let us solve this equation:
************************** 3(2x) + 3(4) = 5****** Ta-da!** Now the x’s are unhooked from the 1’s
***************************** 6x + 12** =* 5
*************************************** 6x =* 5 - 12
******************************************** =* -7
*************************************** x* =* -7/6
:rofl
I’ll see if I can find a Phd in mathematics tomorrow at work.
So it would be 48/212 ???
:gtfo
it doesn’t matter who has what education… it is algebra. and it depends on what you were taught.
Yeah the right way or the wrong way.
I don’t think you guys understand that math isn’t up to interpretaion it’s based on solid rules (not counting theories).
Otherwise we would have space shuttle crashes because of the use of 288 instead of 2 and similar.
I named a rule, laid it out and demonstrated what else there left?
Your auntie rule does not supersede this, this is how multiplication of parenthesis works.
Period.
HVCC Automotive ftw
I would not use space shuttle crashes as an example. NASA crashed the Mars rover due to a failure to convert standard and metric measurements properly. Real world math is useful. This thread is not.
The engineers at Chernobyl and Fukushima thought it was 288.
This thread is hellagay
actually if you distirbuted out the 3 from (9+3) it would be as follows:
48/2*3(3+1)
you cant just multiply 2*3 and ignore the order of operations which just goes to show you cant just distribute whenever you want and move stuff around. Everyone is so used to there being a + sign in front of where the 2 is and distribute first.
I’ll also add i think the answer should be 2, based on my belief that there should be a rule that implied multiplication should come before explicit. But there isn’t a rule and I don’t like how you are going on about how your Russian education far exceeded your american one, and how you refuse to see where you may be wrong in some way.
Lock 1 try 2
Lock 2 try 2
lock 3 try 3
Lock 4 try 2.
(where teh fawk did Kramer get try 3 from? :rofl)
There will be no lock, if you don’t like math stay out.
No because in your own example if it’s
48/2*3(3+1)
It becomes 72(3+1) going left to right
So you’re proving yourself wrong by saying that 3 will be assigned to the parenthesis and don’t out of order of left to right, but somehow that 2 isn’t assigned???
It doesn’t matter what sign is in front, the rule is the rule, distributive property states that it’s equivalent of (18+6) with 2 factored out making it (9+3) and two sitting outside.
That’s why it can be written as 48/(9+3)2 and still be right.
DON’T ASK FUCKING QUESTIONS
