Mason opens the hood of his car and discovers that squirrels have been using his engine compartment to store nuts. If 2 busy squirrels have been stockpiling 30 nuts/day and one sleepy squirrel has been stockpiling 20 nuts/day, all for 40 days, how many nuts are in Mason's car?
First find the number of nuts the two busy squirrels gather per day: 2 squirrels * 30 nuts/day/squirrel = 
<gadget id="calculator">2*30</gadget>
<output>60</output>
60 nuts/day.
Then add the number the sleepy squirrel gathers each day: 60 nuts/day + 20 nuts/day = 
<gadget id="calculator">60+20</gadget>
<output>80</output>
80 nuts/day.
Then multiply the number of nuts gathered daily by the number of days to find the total number of nuts gathered: 80 nuts/day * 40 days = 
<gadget id="calculator">80*40</gadget>
<output>3_200</output>
3200 nuts.
