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 103 + (-66).
Here, it is observed that the numbers 103 and -66 are positive and negative integer respectively.
Evaluate the given expression using above procedure.
Step 1: Subtract the smaller absolute value from the larger absolute value.
Absolute value of |103| = 103 and |-66| = 66.
The smaller absolute value is 66 and the larger absolute value is 103.
Therefore, the difference of the numbers is 103 - 66 = 37.
Step 2: Attach the sign of the integer with large absolute value.
The larger absolute value is 103 and its sign is positive.
So, the result of the sum will have positive sign.
Thus, the value of the expression 103 + (-66) is 37.
