  • @chrissline77 You dont understand shit lucifer. Fuckin Cunt Bitch!!! Your life is fuckin dead.

  • Oh my God I don't understand!!!!!!!!!!!!!!!

  • I learned an awesome model today at an interview, of all places. The "as compared to" model for subtraction. Take "7 - 2". This can be read as "7 as compared to 2", which leads to an answer of "they are comparably 5 apart".

    It also works for subtracting negatives! "7 - -2" can be read as "7 as compared to -2", which leads to an answer of 9 since 7 and -2 are comparably 9 spaces apart!

    So awesome!

  • Shes speaks like if we were stupid and we didnt understand -.-
