Answer:
Yes Sidharth is correct.
Step-by-step explanation:
The absolute value of a number is just the natural number of a number (the positive value of a number). So since Sidharth has a balance of -163 this means that he owes the bank $163, therefore you can find how much he ownes the bank just by determining the absoulte value of the number. Which would be $163, so yes Sidharth is correct.
