Answer
Step-by-step explanation
Any amount in credit means the money is coming into the account. Hence, it is denoted with a positive sign in front of the money.
AND
Any amount in debit means the money is leaving the account. Hence, it is denoted with a negative sign in front of the money.
So,
A credit of $9.19 = +9.19
A debit of $9.19 = -9.19
The absolute value of any number takes only the positive part of that number as answer. That is,
The absolute value of 2 = |2| = 2
The absolute value of -4 = |-4| = 4
