Test case $1$: The initial population of the town was $3$ million, out of which $1$ million people left and $2$ million people entered the town. So, final population $= 3 - 1 + 2 = 4$ million.
Test case $2$: The initial population of the town was $2$ million, out of which $2$ million left and $2$ million immigrated. The final population is thus $2+2-2 = 2$ million.
