<output>6/5 = around 1.2</output>

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

<gadget id="calculator">(6/5) * (1/2)</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">(6/5) - (3/5) - (1/2)</gadget>
<output>1/10 = around 0.1</output>

<result>1/10 = around 0.1</result>
