<gadget id="calculator">2*20</gadget>
<output>40</output>
40 trees by himself.
Each of his brothers cuts down 20*.2=
<gadget id="calculator">20*.2</gadget>
<output>4</output>
4 fewer trees per day.
So they each cut down 20-4=
<gadget id="calculator">20-4</gadget>
<output>16</output>
16 trees.
So for the next 3 days they cut down 20+16*2=
<gadget id="calculator">20+16*2</gadget>
<output>52</output>
52 trees per day.
So they cut down 40+52*3=
<gadget id="calculator">40+52*3</gadget>
