Integers are positive numbers, negative numbers and zero. This means numbers like 0,1,2,3 as well as -1, -2, -3, are integers. Integers do not have any added parts such as decimals or fractions. Therefore, numbers with fractions like 3 1/2 or decimals like -7.5 are NOT integers.

The rule for adding two integers depends on whether the signs of the addends are the same or different. Rule for Adding Tw o Integers: TO ADD INTEGERS W ITH THE SAME SIGN , add the absolute values of the numbers. Then attach the sign of the addends.
