Mathematical puzzles in ancient India were widely circulated because of the introduction of the poet Langfellow. Let's describe it in modern language: a large group of bees, (1/5) flies to the cauliflower, (1/3) flies to the lotus, the difference in the number of two small groups of bees is 3 times to collect honey, and there are 10 around the cherry blossoms fly. How many bees are there in total?
古印度的数学谜题，因诗人郎费罗的介绍而广为流传．下面用现代语言叙述一下：一大群蜜蜂，(1/5)飞向菜花，(1/3)飞往莲花，两小群蜜蜂数量之差的3倍去采蜜，还有10只绕着樱花飞．蜜蜂总数是多少只．
<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

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

<gadget id="calculator">(1/3) - (1/5)</gadget>
<output>2/15 = around 0.133333</output>

<gadget id="calculator">(2/15) * 3</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">1 - (1/5) - (1/3) - (2/5)</gadget>
<output>1/15 = around 0.066667</output>

<gadget id="calculator">10 / (1/15)</gadget>
<output>150</output>

<result>150</result>
