<gadget id="calculator">5 / 4</gadget>
<output>5/4 = around 1.25</output>

<gadget id="calculator">110 * (5/4)</gadget>
<output>275/2 = around 137.5</output>

<gadget id="calculator">300 - (275/2)</gadget>
<output>325/2 = around 162.5</output>

<gadget id="calculator">(325/2) / (5/4)</gadget>
<output>130</output>

<result>130</result>
