The rules to adding integers
if the same sign add the numbers and keep the sign
if different signs subtract the numbers and keep the sign of the bigger number

For example
5+6=11 because it's the same sign
But if you had 8+-12 it would equal negative 4 because they have different signs and the bigger # is negative

For example+12-+6= +6
Or +6-+12 would equal -6 because the smaller number is first

Rules to subtracting integers
*subtract the numbers if the bigger # is first the number is positive if the smaller # is first
the answer is negative

You can also add the numbers
* add the numbers and take the sign of the first # for example: -1-+3 you change the sign of the first number and of the minus sign so it equals negative 4
