<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">13 * (1/2)</gadget>
<output>13/2 = around 6.5</output>

<gadget id="calculator">17 * (1/2)</gadget>
<output>17/2 = around 8.5</output>

<gadget id="calculator">(13/2) + (17/2)</gadget>
<output>15</output>

<gadget id="calculator">360 / 15</gadget>
<output>24</output>

<result>24</result>
