The scientific calculator F-715SG has an extra-large 2-line LCD display and is ideal for problem-solving tasks in connection with teaching, exams and homework. Entries appear on the top line and results on the bottom - up to 10-digit answers and two-digit exponents can be displayed. The primary display digits are 9.6 x 3.96 mm in size, making it easy and quick to read results accurately. This scientific calculator is smart in every way and has all the essential functions that students need in their math and science studies, including basic math, trigonometry, statistics and construction. The F-715SG has a total of 250 functions for advanced problem solving. It has the capacity to store and recall up to 17 calculations, allowing users to explore different patterns and concepts. In addition, internal calculations can be performed with 16 digits, so that the results will be more precise. The F-715SG is both a practical and a more sustainable choice. That's because Canon uses recycled plastic materials to make the bottom case and the hard cover. Used resources get a new life. This scientific calculator is powered by both solar cells and replaceable batteries, so you get continuous reliability and a double safety during exams. Use the energy-saving solar solution when light conditions allow, and switch to backup battery power when needed. The F-715SG also provides plenty of early warnings to indicate that the battery is running low. When not used or touched for seven minutes, the "auto-off" function turns off the calculator to save even more battery resources.
