Step-by-step explanation: -6+(-73)=-79 because the negative number means minus.
-79+(positive)56=-23 because a negative number plus a positive number is adding the positive number meaning you subtract but keep the negative sign
-23+(-33)=-56 because the negative number means minus

Negative-negative=plus (idk why but its meth)
