Printing Calculator with 12 Digit LCD Display Screen, 2.03 Lines/sec, Two Color Printing, Adding Machine for Accounting Use, AC Adapter Included B08FBT9X66

An AC adapter is included so you never have to worry about running out of power. However, if you want to travel, this calculator is also for you. It supports 2 AA batteries (not included), giving you the option of mobility. This is an adding machine and DOES NOT function like a standard desktop calculator. For example, to do the equation 4 - 2, you would need to press “4” then “+” then “2” then “-” then “equals” to get the right answer. Tutorials and examples are provided in the detailed instruction manual.
