MJ100D Plus

The Casio MJ-100D Plus is a tax calculator that features an extra large 10-digit display and some handy functions.

The recheck function allows confirmation of errors by sound when checking calculations. If the user presses an incorrect key when performing a second calculation to check calculation results, a buzzer sounds to alert the user of the error. Automatic calculation of price plus tax, price less tax, discount, selling price, tax amount, discount amount, and margin amount.

Key operations are stored in a buffer, so nothing is lost even during high-speed input. All the mark-up capabilities of an adding machine for simplified cost and profit calculations.
