Simple calculations that can be simplified: (2-((3/4)+(1/3)))/(2/3).
能简算的要简算：(2-((3/4)+(1/3)))/(2/3)．
<gadget id="calculator">3 / 4</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">(3/4) + (1/3)</gadget>
<output>13/12 = around 1.083333</output>

<gadget id="calculator">2 - (13/12)</gadget>
<output>11/12 = around 0.916667</output>

<gadget id="calculator">2 / 3</gadget>
<output>2/3 = around 0.666667</output>

<gadget id="calculator">(11/12) / (2/3)</gadget>
<output>11/8 = around 1.375</output>

<result>11/8 = around 1.375</result>
