Procedure used:
Adding two integers using Absolute Value:
"To add integers with the same sign (both positive or both negative)
Step 1: Add the absolute values of the two integers.
Step 2: Attach the common sign.
To add integers with the different sign (one positive or one negative).
Step 1: Subtract the smaller absolute value from the larger absolute value.
Step 2: Attach the sign of the integer with large absolute value".
Calculation:
Consider the expression -98 + 56.
Here, it is observed that the numbers -96 and 56 are negative and positive integer respectively.
Evaluate the given expression using above procedure.
Step 1: Subtract the smaller absolute value from the larger absolute value.
Absolute value of |-98| = 98 and |56| = 56.
The smaller absolute value is 56 and the larger absolute value is 98.
Therefore, the difference of the numbers is 98-56 = 42.
Step 2: Attach the sign of the integer with large absolute value.
The larger absolute value is 98 and its sign is negative.
So, the result of the sum will have negative sign.
Thus, the value of the expression -98 + 56 is -42.

To evaluate: The value of the expression -98+56.
