It depends on the two numbers.  A negative plus a positive can be either positive or negative.

If the larger number is positive, then adding the negative number will result in a positive.
If the smaller number is positive, then adding a negative number will result in a negative.
If they're equal, then the result is zero.

Addition --
(+3) + (+5) = (+8) -- The signs are both plus, thus add the digits and write a plus value.
(-3) + (+5) = (+2) -- The signs are different, thus take the difference between the digits and write the sign of the larger digit.
(-3) + (-5) = (-8) -- The signs are both minus, thus add the digits and write a negative value.
(+3) + (-5) = (-2) -- The signs are different, thus take the difference between the digits and write the sign of the larger digit.
Subtraction --

(+3) - (+5) = +3 - 5 = (-2) -- Change the sign before the second digit. Take the difference between the digits and write the sign of the larger digit.
(-3) -(+5) = -3 - 5 = (-8) -- Change the sign before the second digit. Add the digits and write a negative value.
(-3) - (-5) = -3 +5 = (+2) -- Change the sign before the second digit. Take the difference between the digits and write the sign of the larger digit.
(+3) - (-5) = +3 +5 = (+8) -- Change the sign before the second digit. Add the digits and write a positive value.
Multiplication --

(+6) x (+3) = (+18) -- The signs are both plus, thus multiply and add a plus value.
(+6) x (-3) = (-18) -- The signs are different, thus multiply and add a minus value.
(-6) x (-3) = (+18) -- The signs are both minus, thus multiply and add a plus value.
(-6) x (+3) = (-18) -- The signs are different, thus multiply and add a minus value.
Division --
(+6) ÷ (+3) = (+18) -- The signs are both plus, thus divide and add a plus value.
(+6) ÷ (-3) = (-18) -- The signs are different, thus divide and add a minus value.
(-6) ÷ (-3) = (+18) -- The signs are both minus, thus divide and add a plus value.
(-6) ÷ (+3) = (-18) -- The signs are different, thus divide and add a minus value.

Think of your starting point as zero. 
 
So, say your first number is -10 as an example, and you were going to ad 11 to that; 
-10 + 11 = 0 - 10 + 11 = 1.
 
~or~ you can switch the places in addition;
-10 + 11 = 11 - 10 = 1, or if you wish to think of zero as your starting point
you would have;
0 - 10 + 11 = 0 + 11 - 10 = 1
 
I hope that helps

Well there are some cases-
1)when you mean the same number is both positive and negative
eg. +10-10=0
2)when you mean different numbers are positive and negative
I)Bigger number is negative and smaller number is positive
eg. +10-9=0
ii)Bigger number is positive and smaller number is negative
eg. +14-8=6
