Subtract and keep the sign of the larger absolute value. With that understanding we can now state the rules for adding terms. If the number was positive change it to negative OR if it was negative change it to positive.

If a number is raised to a power add it to another number raised to a power with either a different base or different exponent by calculating the result of the exponent term and then directly adding this to the other.
