Gaussian integer arithmetic

The work of the German mathematician Carl F. Gauss is universal. Gauss produced with ease in all branches of mathematics. He even made important contributions in astronomy, developing a method of calculating orbits of celestial bodies from a small number of observations. To this day, this method is used to track satellite orbits.

Negative sum?

Let S be the sum of the infinite terms of a PG of strictly positive numbers with ratio 2 and 1 = 1. S = (1 + 2 + 4 + 8 + 16 + 32 +…) => from a to 2, all terms are multiples of 2. If we highlight 2, we have: S = 1 + 2. (1 + 2 + 4 + 8 + 16 + 32 +…) As S = (1 + 2 + 4 + 8 + 16 + 32 +…), we have: S = 1 + 2.

7 is equal to 8?

We start with the following equality, which we assume to be true: a + b = c We can write equality as follows: (8a-7a) + (8b-7b) = (8c-7c) Putting all multiples of 7 on one side and 8 on the other, we have: 8a + 8b-8c = 7a + 7b-7c Putting 7 on one side and 8 on the other, we have: 8 (a + bc) = 7 (a + bc) Dividing both sides by a + bc have: 8 = 7 Obviously this demonstration has an error, because we all know that 8 is not equal to 7 (or does anyone have any questions?
