Answer 1

A half life is the time it takes a substance to decrease by half.

Answer 2

I know that, but am I just supposed to decrease the number of atoms by half each half-life passes and double the amount of years that went by? or something else entirely? XD

Answer 3

Yes. See in the years spot, it shows you the full life of the atom. In the time passed and the years, they are zero, so at the beginning of half life, the atom is at it's fullest. In the end of the half life, just subtract the full term by half.
