Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?
First find the total distance Carson walks along the warehouse's long sides: 600 feet/side * 2 sides = 
<gadget id="calculator">600*2</gadget>
<output>1_200</output>
1200 feet.
Then find the total distance Carson walks along the warehouse's short sides: 400 feet/side * 2 sides = 
<gadget id="calculator">400*2</gadget>
<output>800</output>
800 feet.
Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 
<gadget id="calculator">1200+800</gadget>
<output>2_000</output>
2000 feet.
Then find the number of circles Carson actually walks: 10 circles - 2 circles = 
<gadget id="calculator">10-2</gadget>
<output>8</output>
8 circles.
Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet/circle * 8 circles = 
<gadget id="calculator">2000*8</gadget>
<output>16_000</output>
16000 feet.
