Powerful Set of Functions
What makes this calculator truly stand out is what it can do under the hood. The FX-991ES Plus is packed with over 400 functions. These cover everything from basic arithmetic to more advanced operations suited for higher studies.
Here’s a quick look at some of its key functions:
-
Algebra: Solve linear, quadratic, and polynomial equations. You can also use it to solve simultaneous equations with two or three variables.
-
Calculus: Perform integration and differentiation. This is especially helpful for students in HSC or engineering programs.
-
Matrix & Vector Calculations: Handle matrix operations (up to 3x3) and basic vector calculations—ideal for engineering students.
-
Complex Numbers: Perform calculations with complex numbers in both rectangular and polar forms.
-
Statistical Functions: Includes standard deviation, regression, and other statistical calculations.
-
Base-n Calculations: Convert and calculate in binary, octal, decimal, and hexadecimal—useful for computer science students.
And the best part? Despite having so many features, everything is organized logically, and you won’t need a manual just to find the square root button. That simplicity, combined with power, is a big part of why it’s so widely recommended.
Speed and Accuracy
No student wants to sit around waiting for their calculator to think. The FX-991ES Plus is fast, and it rarely makes you wait—even for complex calculations like solving equations or matrix multiplications.
More importantly, the results are accurate. When you're preparing for a high-stakes exam like BUET admission or a university final, precision matters. This calculator consistently delivers trustworthy results.
The clear screen, responsive buttons, and reliable calculations make it easier to focus on learning and problem-solving, rather than worrying about whether your calculator is doing its job.
Battery and Solar Power Combo
One feature that often gets overlooked—but is incredibly useful—is the dual power system. The FX-991ES Plus runs on solar power and also has a battery backup. That means it works under natural or indoor light and keeps running even during power cuts or in dim exam halls.
In a country like Bangladesh, where power outages are still an occasional problem, this feature adds an extra layer of reliability. You won’t suddenly find yourself stuck in the middle of a mock test because your calculator died on you.
Plus, the battery lasts for years, especially with the solar assist. So, it’s a one-time purchase that keeps working for the long haul.
Price in Bangladesh
Let’s talk cost—because affordability matters.
The Casio FX-991ES Plus is widely available in Bangladesh. You can find it at most stationery stores, coaching centers, and online platforms. The current price generally ranges from BDT 1,400 to BDT 1,800, depending on where you buy it.
While there are cheaper models available, most of them either lack key features or don’t offer the same durability. You might save a few hundred taka with another model, but chances are you’ll miss out on the performance and reliability the FX-991ES Plus offers.
Given what it brings to the table, the price is quite reasonable. For a device that lasts several years and supports you through school and university, it’s a solid investment.
