<output>1/4 = around 0.25</output>

<gadget id="calculator">(1/4) * 18</gadget>
<output>9/2 = around 4.5</output>

<gadget id="calculator">(9/2) + 18</gadget>
<output>45/2 = around 22.5</output>

<gadget id="calculator">1 - (1/4)</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">(45/2) / (3/4)</gadget>
<output>30</output>
