Examples:
-6 + -2 = -8
-10 + -10 =-20
-2 + -5 = -7
When your adding a positive and a negative... well it depends. A positive and a negative are opposites: so they cancel each other out. In other words, when adding a positive and a negative, go to the right of the number line.Examples:-8 + 3 = -5
-1 + 5 = 4
6 + -2 = 8
Theres also another way to do it. Forget the signs! Take the greater number (positive and negative) and put it on the top. Then make a subtraction problem.-10 + 6 =10 - 6 = 4
Which number is greater? that's right, ten! 10 was origanally a negative so your answer is negative.Answer -4

What are the rules in adding integers with like and unlike signs?
To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)

How many integers are there on the number line between the numbers 2.09 and 15.3?
The integers between 2.09 and 15.3 are 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15. So there are 13 integers between 2.09 and 15.3.
What is the sum of the first 100 positive integers?
To find the sum of the first 100 integers, you first add 1 plus 100 (the first and last numbers of the set) and get 101. Do the same with the next two integers, 2 and 99 and you'll get 101. Since you are adding two integers at a time and there are 100 integers between 1 and 100, you'll get 101, fifty times. Therefore, a shortcut would be to simply multiply 101 times 50 and get 5,050.
How do you Add 512 to 6910 as an improper fraction in lowest terms?
