<output>1/5 = around 0.2</output>

<gadget id="calculator">(1/5) * 24</gadget>
<output>24/5 = around 4.8</output>

<gadget id="calculator">(1/5) * 6</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">(24/5) + (6/5)</gadget>
<output>6</output>

<gadget id="calculator">1 + (1/5)</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">6 / (6/5)</gadget>
<output>5</output>

<gadget id="calculator">24 - 5</gadget>
<output>19</output>

<gadget id="calculator">6 / (6/5) / 19</gadget>
<output>5/19 = around 0.263158</output>
