<h2>Binary Number System</h2>
	<p>This section practices the basics of converting between binary and decimal. </p>
	<p>How to use an exercise:</p>
	<ul>
		<li>Follow steps 1-2-3-4, but you may use the "Start" button of an exercise at any time to restart.</li>
		<li>Looking for examples of how to solve a problem? Just click "Start" in step 1, type something for step 2, and move to the step-by-step solution in step 4.</li>
	</ul>
<h4>Exercise 1. Convert Binary to Decimal</h4>
<table>
  <tr>
    <td>1. Generate a random binary number: </td>
    <td><button id="p1StartBtn" type="button" onclick="p1Random0ToN()">Start</button></td>
    <td><p id="p1Data"></p></td>
  </tr>
  <tr>
    <td>2. Please convert it to decimal:</td>
    <td>-</td>
    <td><input id="p1Input"></td>
  </tr>
  <tr>
  <td>3. Now check your answer:</td>
  <td><button id="p1CheckBtn" type="button" onclick="p1CheckResult()" disabled="true">Check</button></td>
  <td><p id="p1Result">-</p></td>
  </tr>
  <tr>
  <td>4. Show the solution:</td>
  <td><button id="p1AnswerBtn" type="button" onclick="p1ShowAnswer()" disabled="true">Solution</button></td>
  <td><p id="p1Answer">-</p></td>
  </tr>
</table>

<h4>Exercise 2. Convert Decimal to Binary - integer</h4>
<table>
  <tr>
    <td>1. Generate a random decimal number: </td>
    <td><button id="p2StartBtn" type="button" onclick="p2Random0ToN()">Start</button></td>
    <td><p id="p2Data"></p></td>
  </tr>
  <tr>
    <td>2. Please convert it to binary:</td>
    <td>-</td>

<h4>Exercise 3. Convert Decimal to Binary - fraction</h4>
<table>
  <tr>
    <td>1. Generate a random decimal fraction: </td>
    <td><button id="p3StartBtn" type="button" onclick="p3Random0ToN()">Start</button></td>
    <td><p id="p3Data"></p></td>
  </tr>
  <tr>
    <td>2. Please convert it to binary (At most 6 bits <br/>after the binary point. Drop additional bits. <br/>Do not round up.):</td>
    <td>-</td>
    <td><input id="p3Input"> (write it as 0.xxxx)</td>
  </tr>
  <tr>
  <td>3. Now check your answer:</td>
  <td><button id="p3CheckBtn" type="button" onclick="p3CheckResult()" disabled="true">Check</button></td>
  <td><p id="p3Result">-</p></td>
  </tr>
  <tr>
  <td>4. Show the solution:</td>
