deathtaker26 Posted March 22, 2015 Author Share Posted March 22, 2015 Solve this math problem:20/2(5+5)I'm sick of seeing it on facebawk answered by so many stupid ass uneducated quacks. (Half my friends list… all 2 of them :'D) Link to comment Share on other sites More sharing options...
Mohenjo Daro Posted March 22, 2015 Share Posted March 22, 2015 It should be just 100 Link to comment Share on other sites More sharing options...

deathtaker26 Posted March 22, 2015 Author Share Posted March 22, 2015 I'm almost 200% sure it's 1 Link to comment Share on other sites More sharing options...
Vus Posted March 22, 2015 Share Posted March 22, 2015 20/2(5+5)I'd say 100.If I recall correctly, brackets go first, so it changes to 20/2(10), which is 20/2*10.Now, they / and * are on the same level, so we go from left side, which makes it 10*10 = 100.Or not, maybe I'm wrong.

deathtaker26 Posted March 22, 2015 Author Share Posted March 22, 2015 but distributive property is a thing…20/2(5+5) = 20/(2*5 + 2*5 ) = 20/(10+10) = 20/20 = 1 Link to comment Share on other sites More sharing options...
deathtaker26 Posted March 22, 2015 Author Share Posted March 22, 2015 I can't remember if distributive property gets rid of brackets or noth though… so it could actually be 1220/2(5+5) = 20/10 + 10 = 2 + 10 = 12 Link to comment Share on other sites More sharing options...
Officer Johnson Posted March 22, 2015 Share Posted March 22, 2015 thats not how you do distributive property Link to comment Share on other sites More sharing options...
Mohenjo Daro Posted March 22, 2015 Share Posted March 22, 2015 You can distribute it if you want, it would go something like…20/2(5+5) to 10(5+5) to (50+50) = 100You do parentheses first, exponents second, multiplication and division third, addition and subtraction forth. And you do those left to right, aka, 20/2 then the 10 and then you multiply it with the parentheses. Link to comment Share on other sites More sharing options...
BeNjO Posted March 22, 2015 Share Posted March 22, 2015 In other words, Crest you're stupid. And your 200% correct statement made you even more stupid. Link to comment Share on other sites More sharing options...
Andiii Posted March 22, 2015 Share Posted March 22, 2015 It's 100 like the others said. Link to comment Share on other sites More sharing options...
deathtaker26 Posted March 22, 2015 Author Share Posted March 22, 2015 That makes no sense, you do distributive property at the beginning of the equation because it has parenthesis.20/2(5+5) = 20/(10+10) = 20/20 = 1 I'm telling you it's 1 Link to comment Share on other sites More sharing options...
Mohenjo Daro Posted March 22, 2015 Share Posted March 22, 2015 And I'm telling you that you're wrong.You cannot MULTIPLY from right to left which is what you are doing, you have to divide then you may distribute since it's the equivalent to (5+5) = 10 which leads to 20/2*10 which would be 10*10=100 Link to comment Share on other sites More sharing options...
BeNjO Posted March 22, 2015 Share Posted March 22, 2015 Using basic math, the answer is one, because:![](http://puu.sh/gLxYD/a93ca14c89.png)= 1but correctly used its actually 100:![](http://puu.sh/gLy6Q/34969a08bf.png)= 100 Link to comment Share on other sites More sharing options...
JeffSventora Posted March 22, 2015 Share Posted March 22, 2015 > That makes no sense, you do distributive property at the beginning of the equation because it has parenthesis.> > 20/2(5+5) = 20/(10+10) = 20/20 = 1 I'm telling you it's 1That means do what's in the parenthesis first, which would be adding those constants. Answer should be 100. Link to comment Share on other sites More sharing options...
deathtaker26 Posted March 23, 2015 Author Share Posted March 23, 2015 the parenthesis are setup for distributive property….and I never multiplied right to left. Link to comment Share on other sites More sharing options...
Mohenjo Daro Posted March 23, 2015 Share Posted March 23, 2015 You don't distribute before multiplying outside the parentheses, in other words, you have been going right to leftIf you want to know the answer then [HERE](https://www.google.com/search?safe=off&q=20%2F2%285%2B5%29&oq=20%2F2%285%2B5%29&gs_l=serp.12..0i71l2.0.0.0.18851.0.0.0.0.0.0.0.0..0.0.msedr...0...1c..62.serp..0.0.0.-3ubsf-AZl0) Link to comment Share on other sites More sharing options...
JohnPony Posted March 23, 2015 Share Posted March 23, 2015 20/(2(5+5)) is equal to 1.20/2(5+5) is equal to 100.Discussion over. Lock this thread and shut up. Link to comment Share on other sites More sharing options...
lexkymbeth Posted March 23, 2015 Share Posted March 23, 2015 To be honest this is how we do it in school (And everywhere else in the world)(Order Of Operations AKA PEMDAS)1. Parentheses first2. Exponents3. Multiplication and Division (left-to-right)4. Addition and Subtraction (left-to-right)20/2(5+5) Parentheses first:20/2(10)No Exponents, SkipMultiply/Devide left to right20/2 = 1010(10)Ans = 100Basic Math#100%inmathEdit:> the parenthesis are setup for distributive property….> > and I never multiplied right to left.You **only**use distributive property for lettersLikeso:5(x+3) = 5x + 15yea lock the thread Link to comment Share on other sites More sharing options...
Colonello Posted March 23, 2015 Share Posted March 23, 2015 Yup it's 1\. Just as Lex said you use the Order of Operations. I'm surprised that so many people don't know about it. I learned it in 3rd grade. ;-; Link to comment Share on other sites More sharing options...
