If you’re a student preparing for JEE, NEET, GATE, or other competitive exams, you already know the value of a good calculator.

The Casio fx-115ES PLUS 2nd Edition is the latest scientific calculator designed to support complex calculations across subjects like Physics, Chemistry, and Engineering Math.

With a Natural Textbook Display, 417 built-in functions, and dual power for reliability, it’s ideal for Indian students at every academic level.

Let’s dive into what makes this calculator special—and whether it’s the right pick for you!

Design & Display: Simple, Smart & Textbook-Friendly

One of the standout features of this model is its Natural Textbook Display. This allows you to see fractions, roots, powers, and formulas exactly how they appear in textbooks.

Display Highlights:

• High-resolution 2-line display
• Shows input and output in textbook format
• Clean, non-reflective screen for better visibility
• Slim, durable design with a hard protective case

Unlike the ClassWiz UI found in models like the Casio FX-991CW, this calculator sticks to a traditional interface, which many students find less distracting and quicker to operate.

• Matrix and vector calculations
• Statistical analysis: standard deviation, regression
• Logical operations, inequality solving
• Engineering symbols and constants

While it doesn’t feature QR code graphing like the Casio FX-991CW or FX-991EX, it offers everything most Indian exams allow in non-programmable calculators.
