There are six peregrine falcons and 40 pigeons nesting in Malcolm's skyscraper. Each pigeon has 6 chicks. If the peregrines eat 30% of the pigeons, how many pigeons are left?
First find the total number of chicks: 40 pigeons * 6 chicks/pigeon = 
<gadget id="calculator">40*6</gadget>
<output>240</output>
240 chicks.
Then add that to the number of adult pigeons to find the total number of pigeons: 240 chicks + 40 pigeons = 
<gadget id="calculator">240+40</gadget>
<output>280</output>
280 pigeons.
Then multiply that number by 30% to find the number of pigeons that were eaten: 280 pigeons * 30% = 
<gadget id="calculator">280*30*.01</gadget>
<output>84</output>
84 pigeons.
Then subtract that number from the total number of pigeons to find the number that are left: 280 pigeons - 84 pigeons = 
<gadget id="calculator">280-84</gadget>
<output>196</output>
196 pigeons.
