Complete the additions using tokens: i) (-3)+(-2) ii) (+5)+(-7)

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
