I don't really understand the rules for adding and subtracting integers. Can someone explain them to me?
These two sites have excellent explanations.

Thanks so much! :)
I don't get it either help us!
Of course! I'd be happy to explain the rules for adding and subtracting integers.
To add integers, you follow these steps:
1. Identify the signs of the numbers you wish to add.
2. If the signs are the same (both positive or both negative), simply add the absolute values of the integers and keep the same sign.
3. If the signs are different (one positive and one negative), subtract the smaller absolute value from the larger absolute value and give the result the sign of the number with the greater absolute value.
For example, let's say you want to add 5 and -3. Since the signs are different, you subtract the smaller absolute value (3) from the larger absolute value (5), resulting in 2. Since the number 5 is positive, the sum will be positive, giving you the final answer of 2.
Now let's move on to subtraction:
1. Start by converting the subtraction problem to an addition problem. This is done by changing the sign of the number being subtracted. For example, if you have 7 - 3, you can rewrite it as 7 + (-3).
2. Apply the rules for addition to find the sum. Following the rules I explained earlier, you add the absolute values and apply the appropriate sign.
For instance, if you have 7 - 3, you would rewrite it as 7 + (-3). Since the signs are different, you subtract the smaller absolute value (3) from the larger absolute value (7), resulting in 4. Since the number 7 is positive, the difference will be positive, giving you the final answer of 4.
I hope these explanations help clarify the rules for adding and subtracting integers! If you have any further questions, feel free to ask.
