## Long description

The Basic Calculator Casio SL-310UC-WE Pocket 10 Digits White is a compact, battery-and-solar powered pocket calculator designed for everyday arithmetic, tax and profit calculations. It features a single-line, extra-large 10-digit display and plastic keys for durable, easy operation. The device supports two-way power, time calculations and a function command indicator that shows the current arithmetic operation on the screen, helping to reduce input errors during quick use.
Advantages
This Casio pocket calculator combines solar and battery power to ensure reliable operation in varying light conditions. The extra-large 10-digit display improves readability for numerical entries and results. Key rollover stores rapid key presses in a buffer so no input is lost during fast calculation. Dedicated tax and profit margin functions allow quick computation of price plus tax, price less tax, discount amounts and margin percentages without manual conversions. The clearly marked function symbols on the display and ergonomically designed plastic keys make everyday use straightforward and efficient.

How to use
Turn the calculator on and enter numbers using the plastic keys; the function command sign on the display indicates the active operation (+, -, ×, ÷). Use the tax keys to calculate price plus tax or price less tax by entering the amount and selecting the appropriate tax function. To compute profit margin or discount values, enter cost and selling price or use the dedicated percent key to obtain margin percent and related amounts. For time calculations, input hours, minutes and seconds in sequence and perform arithmetic operations as needed. The device will automatically switch to battery power when ambient light is insufficient for solar operation.
Usage recommendations
To extend battery life and ensure reliable solar operation, use the calculator in well-lit areas when possible and avoid prolonged storage in dark places. Clean the plastic keys and display gently with a soft, dry cloth. For frequent tax or margin tasks, preset the local tax rate before calculations to save time during repeated use.
