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

<gadget id="calculator">4 + 3</gadget>
<output>7</output>

<gadget id="calculator">4 / 7</gadget>
<output>4/7 = around 0.571429</output>

<gadget id="calculator">(3/5) * (4/7)</gadget>
<output>12/35 = around 0.342857</output>

<gadget id="calculator">(2/5) - (12/35)</gadget>
<output>2/35 = around 0.057143</output>

<gadget id="calculator">60 / (2/35)</gadget>
