What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Tessa had $90 in her checking account.

Balance = $90

She paid her cable/internet bill for $60.

Balance = $90 - $60 = $30

She deposited $50 from her part-time job.

Balance = $30 + $50 = $85

She wrote a check for $65 to pay her credit card bill.

Balance = $85 - $65 = $20

Hence, Tessa's account balance after all of this transaction is $20.
