6÷2(1+2) = ? The Correct Answer Explained By Math Major
What is 6÷2(1+2) = ? This problem went viral and generated millions of comments on Facebook, Twitter, YouTube and social media sites. I explain how to get the correct answer by using the modern interpretation of the order of operations. I also explain how you would get a different answer under historical usage of the division symbol. (Note: some people write 6/2(1 + 2) = but this has the same answer.)
*I get many, many emails about this problem. Before you send an email, check out my blog post or in the links provided below which address every concern I have received so far. If you write to me about this be advised I probably will not respond.
