Could someone explain the fish equation from Stanley Parable?

42

if you combine the 4 and the 1 from 541 you can add them to make a 5, that 5 and the remaining 5 from 541 are one in the same. so working with interger values, the difference between 5 and 7 is 2 which is also the same as if you had added 5 4 and 1 to make 10 and then got the difference from the remaining 8. This requires the 2 to go up to the numerator. now 2 is the answer for both the problems stated above, and if you added both those answers of 2 together you get 4. since that 4 came to be because of those winning 2s the 4 gets to wear a hat in the shape of a 2. This math is obviously wrong but it sounds smart so it equals a grade of an F-ish
