<h1 align="center">Even and Odd Numbers</h1>
<p align="center"><img src="images/even-odd.svg" alt="even and odd numbers" /></p>
<h2>Even Numbers</h2>
<p>Any <a href="../whole-numbers.html">integer</a> that can be divided exactly by 2 is an <b>even number</b>.</p>
<p>The last digit is <span class="large">0</span>, <span class="large">2</span>, <span class="large">4</span>, <span class="large">6</span> or <span class="large">8</span></p>
<div class="example">
<p>Example: &minus;24, 0, 6 and 38 are all even numbers</p>
</div>
<h2>Odd Numbers</h2>
<p>Any integer that <b>cannot</b> be divided exactly by 2 is an <b>odd number</b>. </p>
<p>The last digit is <span class="large">1</span>, <span class="large">3</span>, <span class="large">5</span>, <span class="large">7</span> or <span class="large">9</span></p>
<div class="example">
<p>Example: &minus;3, 1, 7 and 35 are all odd numbers</p>
</div>
<p>Odd numbers are in between the even numbers.</p>
<h2>Adding and Subtracting </h2>
<p>When we add (or subtract) odd or even numbers the results are always:</p>
<table border="0" align="center" cellpadding="5">
<tr align="center">
<th>Operation</th>
<th>Result</th>
<th>Example<br />
(<span class="style1">red</span> is odd, <span class="style2">blue</span> is even)</th>
</tr>
<tr align="center">
<td>Even + Even</td>
<td>Even</td>
<td class="number"><span class="style2">2</span> + <span class="style2">4</span> = <span class="style2">6</span></td>
</tr>
<tr align="center">
<td>Even + Odd</td>
<td>Odd</td>
<td class="number"><span class="style2">6</span> + <span class="style1">3</span> = <span class="style1">9</span></td>
</tr>
<tr align="center">
<td>Odd + Even</td>
<td>Odd</td>
<td class="number"><span class="style1">5</span> + <span class="style2">12</span> = <span class="style1">17</span></td>
</tr>
<tr align="center">
<td>Odd + Odd</td>
<td>Even</td>
<td class="number"><span class="style1">3</span> + <span class="style1">5</span> = <span class="style2">8</span></td>
</tr>
</table>
<p>(The same thing happens when we subtract instead of adding.)</p>
<h2>Multiplying</h2>
<p>When we multiply odd or even numbers the results are always:</p>
<table border="0" align="center" cellpadding="5">
<tr align="center">
<th>Operation</th>
<th>Result</th>
<th>Example<br />
(<span class="style1">red</span> is odd, <span class="style2">blue</span> is even)</th>
</tr>
<tr align="center">
<td>Even &times; Even</td>
<td>Even</td>
<td class="number"><span class="style2">4</span> &times; <span class="style2">8</span> = <span class="style2">32</span></td>
</tr>
<tr align="center">
<td>Even &times; Odd</td>
<td>Even</td>
<td class="number"><span class="style2">4</span> &times; <span class="style1">7</span> = <span class="style2">28</span></td>
</tr>
<tr align="center">
<td>Odd &times; Even</td>
<td>Even</td>
<td class="number"><span class="style1">5</span> &times; <span class="style2">8</span> = <span class="style2">40</span></td>
</tr>
<tr align="center">
<td>Odd &times; Odd</td>
<td>Odd</td>
<td class="number"><span class="style1">5</span> &times; <span class="style1">7</span> = <span class="style1">35</span></td>
</tr>
</table>
<h2>Odd Fact</h2>
<p>Every odd number has an &quot;e&quot; in it! </p>
