The second transaction is just as simple: purchase a second cow for $1,100 and sell it for $1,300. Don’t be tempted to connect it too soon to the first; instead, take the same gradual approach. Again, the net gain is $200 after spending 1,100 and receiving 1,300. The reward is tangible, gradual, and obvious; nothing supernatural happens here. Every transaction conveys a tale of return on investment. When viewed in this manner, the fog in the mind starts to clear.
The last step is just aggregation once each story has been comprehended separately. When the two mini-profits are combined, $200 from the first cow and $200 from the second cow come to $400. This is the right response; it’s straightforward, tasteful, and fulfilling. Examining the totals from a “zoomed-out” view is another method to confirm this. $800 plus $1,100, or $1,900, is the total amount spent on both purchases. The total amount earned is $2,300, which is $1,000 plus $1,300. We get exactly the same $400 when we deduct the total amount spent from the total amount earned ($2,300 minus $1,900). The fact that both macro- and micro-level approaches lead to the same outcome is comforting and serves as a reminder that patience and careful consideration are necessary to achieve clarity.
This is actually a psychological lesson. The majority of the challenges are not related to math; a third grader may perform calculations like $1,000 minus $800 and $1,300 minus $1,100. Keeping several sequential processes distinct and fighting the brain’s tendency to oversimplify are the only cognitive challenges. This puzzle demonstrates how quickly a perfectly solvable problem may become complex if we rush through it.
