Basic Calculator Casio SL-310UC-RD Pocket Red 10 Digits Solar

The Casio SL-310UC-RD Pocket Red is a compact basic calculator with a 10-digit single-line display designed for everyday arithmetic tasks. It supports tax and profit margin calculations, time calculations, and offers two-way power (solar plus battery) for reliable use in variable light conditions. The calculator features an extra-large display and plastic keys for comfortable, portable operation.

Advantages

The calculator provides automatic tax functions for price with tax, price without tax, tax amount, discounts and margin amounts. Time calculation enables direct entry and computation of hours, minutes and seconds. A function command sign on the display shows the current operation (+, -, ×, ÷). Key rollover stores rapid key presses in a buffer to prevent input loss. The solar-and-battery two-way power reduces battery use when light is available. The “%” key allows quick percentage and profit margin calculations.
