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!
