<gadget id="calculator">171 - 6</gadget>
<output>165</output>

<gadget id="calculator">1 / 8</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">1 - (1/8)</gadget>
<output>7/8 = around 0.875</output>

<gadget id="calculator">1 + (7/8)</gadget>
<output>15/8 = around 1.875</output>

<gadget id="calculator">165 / (15/8)</gadget>
<output>88</output>

<result>88</result>
