ELEVEN SR-270N Black

The Eleven SR-270N scientific calculator is designed for secondary school and university students. It has 240 integrated functions for mathematical operations, from fractions to statistical calculations. The two-line display shows both the calculation and the result at the same time. Thanks to its dual power system, the calculator runs on both solar energy and a battery. It includes a hard slide-on cover that protects the device from damage when you're on the move.

Mathematical functions

The calculator helps you solve complex problems with its wide range of functions. In addition to basic operations with powers, roots, and fractions, it also supports trigonometric and hyperbolic functions. For statistics and data analysis, standard deviation calculations and regression analyses are available. The calculator also handles permutations and combinations. It is designed for technical fields. The correction function lets you fix a number you've entered without having to delete the entire calculation.

Design and power

The two-line display lets you see the expression you've entered and its result at the same time. The dual power system ensures operation. In sufficient light, the calculator uses the solar panel and saves the battery. In low light conditions, it automatically switches to power from the AAA battery. The hard cover protects the device from scratches and dirt, making it suitable for carrying in your backpack or bag every day.
