Let's count them!
the initial number of zebras, let's call it z:
A population of zebras experienced ten births
this means:
z+10
six deaths to predation
this means:
z+10-6
three deaths to disease
this means:
z+10-6-3
three individuals joining the population
this means:
z+10-6-3+3
and zero individuals leaving
this means:
z+10-6-3+3+0
now, let's sum it up:
z+10-6-3+3+0=z+10-6-3+3=z+10-6=z+4
so the population grew (by 4 individuals); it's a positive population growth!
