Basics:
Positive + Positive= Positive
Positive + Negative= Positive or Negative, depends on the problem
Negative + Negative= Negative
Example: -15 + 7= ?
Basically what you are doing is subtracting 7 from 15. 15 - 7= 8
Now, you turn the 8 into negative 8. -15 + 7= -8. You are doing this because let's say you have good candy and bad candy. You have 15 bad candy. You add 7 good candy. 7 of the 15 bad candy cancel out the 7 good candy. So, now you are doing 15 bad candy minus 7 bad candy, so you are left with 8 bad candy!
o= posotive x=negative. This is an easier way to think of it.
x x x x x x x x x x x x x x x
o o o o o o o= These posotive chips cancel out 7 of the negative chips right above them. Now the left over chips is what your answer is, whether it is posotive or negative!
You'll get the hang of it don't worry. ;)

What is the sign for multiplication and addition?
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.

What are the rules for adding and subtracting integers?
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
