## Long description

The Casio WM-320MT Pocket Calculator (Black Yellow) is a compact 12-digit calculator with a single-line extra-large display designed for clear, on-the-go calculations. It supports two-way power (solar + battery) to ensure operation in varying light conditions and includes functions for tax, margin and cost/sell calculations. The device features plastic keys engineered for easy operation and key rollover to buffer inputs during fast typing.
Advantages
The extra large display improves readability of numbers and operation symbols. Two-way power uses solar energy when light is sufficient and battery backup when it is not, extending usable life. Key rollover stores rapid key operations in a buffer so no input is lost during high-speed entry. Dedicated functions for cost/sell/margin and tax calculations simplify common retail and accounting tasks, while the percent key provides quick access to profit and discount computations.
Suitable for
Retail cashiers and shop use
Small business accounting and pricing
On-the-go calculations for students and professionals
Tax and profit margin calculations
