a. Subtracting 4 is the same as adding $\boxed{(-4)}$

b. Subtracting -7 is the same as adding $\boxed{(7)}$

c. Subtracting a positive number is the same as adding a

\boxed{negative} number, where that $\boxed{?}$ is opposite of the original number

d. Subtracting a negative number is the same as adding a

$\boxed{?}$ number, where that $\boxed{?}$ is opposite of the original number

ok they are trying to teach about using counters to add

but $\boxed{?}$ was kinda on of those boolean confusions
