<gadget id="calculator">12 / 100</gadget>
<output>3/25 = around 0.12</output>

<gadget id="calculator">1 - (3/25)</gadget>
<output>22/25 = around 0.88</output>

<gadget id="calculator">13 / 100</gadget>
<output>13/100 = around 0.13</output>

<gadget id="calculator">1 + (13/100)</gadget>
<output>113/100 = around 1.13</output>

<gadget id="calculator">1 * (22/25) * (113/100)</gadget>
<output>1_243/1_250 = around 0.9944</output>

<result>1_243/1_250 = around 0.9944</result>
