    But we know that 7+7/7+7*7-7 = 7*(1+1/1+1*1-1) so the answer is actually 14.

      7*(1+1/1+1*1-1) this is wrong
      actully should say 7*(1 + 1/7 + 7 - 1) =
      7(1/7 + 49/7) = 7*50/7 = 50

    The rules of mathematics state that you start with multiplication and division first. Do not try to solve a mathematical problem like you're reading a paragraph (From left to right)
