Here are the solutions to the problems:

19) Complete the additions using tokens:

i) $(-3) + (-2)$
When adding two negative numbers, add their absolute values and keep the negative sign.

$$(-3) + (-2) = -(3+2) = -5$$

The sum is $\boxed{-5}$.

ii) $(+5) + (-7)$
When adding numbers with different signs, find the difference between their absolute values and use the sign of the number with the larger absolute value.
The absolute value of $+5$ is 5.
The absolute value of $-7$ is 7.
The difference is $7 - 5 = 2$.
Since 7 (from $-7$) has a larger
