For a class reunion, the number of absentees in the morning is 1/7 of the number of attendees, and in the afternoon, one person is unable to attend because of something else, so the number of absentees is 1/6 of the number of attendees.

<gadget id="calculator">1 / 6</gadget>
<output>1/6 = around 0.166667</output>

<gadget id="calculator">(1/6) + 1</gadget>
<output>7/6 = around 1.166667</output>

<gadget id="calculator">1 / 7</gadget>
<output>1/7 = around 0.142857</output>

<gadget id="calculator">(1/6) - (1/7)</gadget>
<output>1/42 = around 0.02381</output>

<gadget id="calculator">(7/6) / (1/42)</gadget>
<output>49</output>

<gadget id="calculator">49 * (1/7)</gadget>
<output>7</output>

<gadget id="calculator">49 + 7</gadget>
<output>56</output>

<result>56</result>
