Lemma:
4 = 5

Bewijs:
16 - 36 = 25 - 45
<=> 16 - 36 + 4,5² = 25 - 45 + 4,5²
<=> 4² - 2*4,5*4 + 4,5² = 5² - 2*4,5*5 + 4,5²
<=> (4 - 4,5)² = (5 - 4,5)²
<=> 4 - 4,5 = 5 - 4,5
<=> 4 = 5

Wat te bewijzen was.

Lemma:
5 = 7

Bewijs:
5 + 2 = 7
<=> 5 * (5 + 2) = 5 * 7
<=> 25 + 10 = 35
<=> 25 + 10 - 35 = 35 - 35
<=> 25 + 10 - 35 = 35 - 35 - 14 + 14
<=> 25 + 10 - 35 = 35 + 14 - 49
<=> 5 * (5 + 2 - 7) = 7 * (5 + 2 - 7)
<=> 5 = 7

x = 0.999...
10x = 9.999...
10x-x = 9.999...-0.999...
9x = 9
x = 1
0.999... = 1

of

1/3 = 0.333...
3/3 = 0.999...
1 = 0.999...

 lim      1/n = 0
n->inf

Dus, 1/inf is idd 0.

Ok, dat is geen bewijs, maar gewoon een manier van opschrijven.
