Did you know that 2 times 2 is 1? My classmate was just pointing out that my professor misspoke (I’m posting this from class because I take notes on my laptop) when he, the professor, said 2 times 2 is 0 but how it’s actually equal to 1. Actually, my classmate is correct because we’re doing 2 times 2 modulus 3, which does happen to equal 1. But after twelve years of public school and four years of college, hearing “2 times 2 is” followed by anything other than “4″ is just weird. Now, back to my note-taking…
