1 + 3 = 4
3 + 1 = 4
After he introduces this formula:

(√x)² = x
The first equation is then reintroduced to:

(√1)² + (√1)² = (√2)²
(√1)² + (√3)² = (√4)²
(√3)² + (√1)² = (√4)²
I understand this, since the formula above says the square root of any number squared will equal the number.

The author then divides the first two numbers x and y by the answer and he is given the answer 1. + 1 = 2
1 + 3 = 4
3 + 1 = 4
