	<title>Percentages</title>
    
    <p>Percentages are calculated using the % symbol.</p>
    <p>When added or subtracted the percentage symbol resolves to one percent of the value being added or subtracted from. The following equation calculates the price of a $140 item with 15% tax (140 + (15÷100)×140).</p>
    <example>
    <p>140+15%</p>
    </example>
    <p>In all other cases the percentage symbol resolves to a fraction out of 100. The following equation calculates one quarter of 80 apples ((25÷100)×80).</p>
    <example>
    <p>25%×80</p>
    </example>
