Rule: The sum of any integer and its opposite is equal to zero.

Explanation: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

To add two numbers with the same sign, first add the two numbers ignoring the sign and then put their common sign before the answer.

To add two numbers with the opposite sign, ignore their signs and subtract the smaller number from the bigger number. Then put the sign of the bigger number before the answer.

To add or subtract integers we first look at the signs of the integers.

To add or subtract two integers,first look at the signs of those two integers.

To add two numbers with the opposite sign, and subtract the smaller number from the bigger number. Then put the sign of the bigger number before the answer.

Here the bigger number 34 is negative and the smaller number 16 is positive. We need to subtract 16 from 34 and the result will be negative.

$-  34  +  16  =  -  18 $
