2 = 3


-6 = -6

4 - 10 = 9 - 15

22 - 2 * 5  = 32 - 3 * 5

22 - 2 * 5 * 2 / 2 = 32 -  3 * 5* 2 / 2

22 - 2 * 5 * 2 / 2 = 32 - 2 * 3 * 5 /  2

25 / 4 + 22 - 2 * 5 * 2 / 2 = 25 / 4 + 32 - 2 * 3 * 5 /  2

(5 / 2) 2 + 22 - 2 * 5 * 2 / 2 = (5 / 2) 2 + 32 - 2 * 3 * 5 /  2

22 - 2 * 2 * 5 / 2 + (5 / 2) 2 = 32 - 2 * 3 * 5 /  2 + (5 / 2) 2

αλλά (α - β) 2  = α2 - 2αβ + β2

για α = 2 και α = 3 (!?) και β = 5 / 2 έχουμε

(2 - 5 / 2) 2 = (3 - 5 / 2) 2

2 - 5 / 2 = 3 - 5 / 2

2 = 3 !!!!!!!!!!!!!!!!!!!!!!
