title: I was asked to write a "sentence" with operators (operator precedence)
body: <p>I'm completely new in programming and Python, and my teacher gave me the instructions to write an equation:</p>
  <p>c = month ≡ day ∨ day ¬ onth</p>
  <p>where ≡ is the identity, ∨ the &quot;or&quot; and ¬ the (logical) negation. I don't really know how to do this, because when I try typing</p>
  <pre><code>c=month is day or (day not month)
  </code></pre>
  <p>Python tells me, that I made a syntax error and I don't know how to fix it. I'm not sure about operator precedence too. I hope you understand my problem as I find it quite hard to tell what's going on because English isn't my first language.</p>
