Great value for money
Works just like the expensive brands but at a fraction of the cost. The display is clear and easy to read. Only minor issue is the case feels a bit flimsy, but the calculator itself is solid.

Reliable workhorse
I've been using Deli calculators for years in my university courses. This model is an upgrade with a better screen and faster processing. No lag when calculating complex equations.

Perfect for my Accounting exams
This calculator has all the functions I need for my CPA preparation. The buttons are responsive, and the dual power source ensures it never dies during a test. Highly recommended for students.

Good for middle school and up
Bought this for my son who is in 8th grade. It handles everything from basic algebra to advanced geometry. The instruction manual could be more detailed, but there are plenty of tutorials online.

Essential for Engineering Students
I use this daily for calculus and physics problems. The trigonometric functions are accurate, and the menu system is intuitive. It survived a drop from my desk without any issues!
Q: Can it perform matrix and vector calculations?
A: This model supports basic matrix operations such as addition, subtraction, and multiplication, as well as determinant calculation. It does not support advanced vector cross products found in higher-end graphing models.
Q: Is this calculator allowed in the SAT and ACT exams?
A: Yes, the Deli DL-82ES Plus is generally permitted for SAT and ACT exams as it does not have graphing capabilities or QWERTY keyboards. However, we always recommend checking the latest official exam guidelines before test day.
Q: Is the hard case sold separately if I lose mine?
A: Currently, the protective hard case is only available as part of the original package. We suggest keeping the box or purchasing a universal calculator sleeve for protection if the original case is lost.
Q: How do I reset the calculator if it freezes?
A: To reset the device, simply press the small 'RESET' hole on the back using a paperclip or similar thin object. This will restore factory settings without damaging the unit.
Q: Does it come with batteries included?
A: Yes, the package includes one LR44 battery pre-installed. Additionally, the solar panel allows the calculator to function in well-lit environments even if the battery runs low.
