Scientific calculator TEKA Milan M240, desktop, 12-digit, 2-line display, battery/solar, pink

TEKA Milan M240 is a desktop scientific calculator designed for education and professional use, offering a 12-digit capacity and a 2-line display that shows expression and result simultaneously. The compact pink housing includes a translucent hard-wearing protective cover and a 10+2 character reading screen. The unit is powered by two AAA batteries with solar backup and comes with instructions. Its dimensions are 16.7 x 8.4 x 1.9 cm.

Advantages

The calculator integrates 240 built-in functions, including 124 scientific functions, enabling trigonometric, parabolic and hyperbolic calculations as well as statistical and combinatorial operations. A two-line display and cursor keys allow easy review and editing of expressions. Additional features include memory storage for variables and averages, automatic fraction calculations, up to 24 levels of bracket structure and multiple angle unit modes (grads, degrees, radians). The design includes large, structured keys for comfortable data entry and a translucent protective cover for increased durability.

Suitable for

• Secondary school and university mathematics and science courses
• Engineering calculations and technical problem solving
• Statistical analysis, regression and data summaries
• Home study, classroom and office use where reliable scientific calculations are required

How to use

Insert the two AAA batteries provided and position the calculator in a well-lit area to enable solar backup. Use the two-line display to enter expressions and verify the formula on the top line while reading results on the bottom line. Navigate within expressions using the cursor keys to correct or review entries before confirming a calculation. Select angle units (degrees, grads, radians) as required for trigonometric operations and switch display notation between SCI, FIX and ENG for result formatting. Use the memory functions to store variables or averages and the statistical menus to perform regressions and summary calculations. The included instructions explain menu navigation and the location of dedicated keys for fractions, combinations, permutations and random number generation.

Usage recommendations

Use the protective translucent cover when transporting the calculator to avoid key wear. For sustained accuracy in repeated classroom or field use, replace AAA batteries as soon as low-power indications appear and keep the solar panel unobstructed. Consult the instruction leaflet for examples of regression and bracketed expression entry to make full use of the calculator's advanced functions.
