<p>Shown above are a few arithmetic operations. BQN manages to pass as a normal programming language for three lines so far. That's a big accomplishment for BQN! Earth's a confusing place!</p>
-<p>The number of spaces between <em>primitive functions</em> like <code><span class='Function'>+</span></code> and <code><span class='Function'>-</span></code> and their <em>arguments</em> doesn't matter: you can use as much or as little as you like. No spaces inside numbers, of course.</p>
+<p>The number of spaces between <em>primitive functions</em> like <code><span class='Function'>+</span></code> and <code><span class='Function'>-</span></code> and their <em>arguments</em> doesn't matter: you can use as much or as little as you like. No spaces inside numbers, of course. On that note, there's a special minus sign <code><span class='Number'>¯</span></code> for use as part of a number, which you can see in the output <code><span class='Number'>¯1.5</span></code> above (since <code><span class='Function'>-</span><span class='Number'>1.5</span></code> consists of a function and a number it's often less convenient to use).</p>
