Answer: 2

The paycheck would be added to the existing balance, and the checks written would be subtracted. The realistic amounts in the question would require considerable time for the arithmetic to be done by hand, but the values can be entered into the calculator in one continuous string as they are presented in the expression.

New balance = Old balance + paycheck
    deposited - checks written
New balance = 1219.17 + 2425.66 - 850.00
    - 235.89 - 418.37
New balance = $2140.57
