If you're looking at 2 positives (2 paychecks), the sum is positive. If you're looking at 2 negatives (2 bills), the sum is negatives. If you're looking at one of each, the result is determined by size (absolute value). If the paycheck is bigger than the bill, you have money left over after paying it (positive). If the bill is bigger than the paycheck, you'll still owe (negative). Understanding this is essential to survival in any human economy, even if the numbers represent sheep and goats.

the sum will take the sign of the largest (absolute value)of the two numbers.
If both are positive the result is positive.
If both are negative the sum is negative.
The sum will be zero only if one number is negative and one positive with the numbers equal to each other.

If the two numbers are positive, the sum is positive.
If the two numbers are negative, the sum is negative.
If the two numbers are opposite signs of the same number, the sum is 0.
If the two numbers are opposite signs, the sum will take on the sign of the larger number. Ex: -9 + 7 = -2

Look at the signs of the two numbers.
If they are both positive, their sum will be positive
If they are both negative, their sum will be negative.
If one is positive and one is negative, determine which number (ignoring the sign) is larger.
If the negative number is larger, the sum of the two numbers will be negative.
If the positive number is larger, the sum will be positive.
If the two numbers are the same, the sum will be zero.
If one number is zero, determine the sign of the sum using the sign of the other number.
If it is positive, the sum will be positive.
If it is negative, the sum will be negative.

If two numbers are positive, the sum is +. If 2 are -, the sum is also -. If you add positive and negative, whichever has a bigger absolute value, use that number's +or -. If the absolute values are equal, the sum is 0

If the numbers are of the same sign, it is evident that the sum will be of that sign also. If the numbers are of opposite sign, the one of larger magnitude will predominate, unless they are the same magnitude in which case the sum is zero.

If the two are valuable, their sum would desire to be valuable. if the two are adverse, their sum is adverse. in any different case, if the valuable quantity seems extra effective than the adverse, the sum is valuable. If the adverse quantity is extra effective than the valuable quantity, the sum is adverse. be conscious comparable rules for transformations. each so often, this is confusing to wager. distinction: -5, -8 valuable distinction: -8, -5 adverse and so on.

If both numbers are positive
sum of two numbers is positive.
If both numbers are negative
sum of two numbers is negative.
If either number is negative
and negative number > positive number
sum of two numbers is negative.
If either number is negative
and postive number > negative number
sum of two numbers is positive.
If either number is negative
and postive number = negative number
sum of two numbers is zero.
