<gadget id="calculator">60*.5</gadget>
<output>30</output>

So they each produce 60+30=
<gadget id="calculator">60+30</gadget>
<output>90</output>
90 lemons.
He has 50*30=
<gadget id="calculator">50*30</gadget>
<output>1_500</output>
1500 trees.
So every year he produces 1500*90=
<gadget id="calculator">1500*90</gadget>
<output>135_000</output>
135000 lemons.
That means he produces 135000*5=
<gadget id="calculator">135000*5</gadget>
<output>675_000</output>
675,000.
