For students in Dhanmondi coaching centres, engineers solving thermal load calculations in Uttara, and professionals preparing BCS quantitative papers late into a Dhaka evening — the Casio FX-991EX sits quietly on your desk and never lets you down. It does not ask for attention. It simply answers every question you put to it, precisely and immediately.
Five hundred and fifty-two built-in functions means the calculation you need — whether a matrix inverse, a definite integral, or a standard deviation for a data set — is always there, accessible in the same number of key presses it was yesterday and will be a year from now. The natural textbook display shows your working exactly as it appears on the exam sheet, so nothing is lost in translation between paper and screen.
A built-in QR code connects each result to a graphical view on your phone via the Casio EDU+ app, so patterns and curves that once required a separate device now appear in seconds. Solar and battery dual power means the calculator continues working through bright exam halls and dimly lit study corners in Chittagong or Cox’s Bazar without interruption.
The hard black casing survives years inside student bags — many buyers across Bangladesh report four or more years of daily use without a single key failing. It is non-programmable and permitted in SSC, HSC, BUET admission, and BCS examinations. A 1-year warranty on manufacturing faults supports every session from the first class to the last exam.

552 Functions
There is one scientific calculator that SSC students in Sylhet, BUET engineers in Dhaka, and BCS candidates in Rajshahi all quietly rely on — and the Casio FX-991EX ClassWiz Scientific Calculator is that calculator. It costs ৳2,300 at eNField-BD. It covers every calculation Bangladesh’s toughest examinations require. Moreover, it works exactly the same on the first day of school as it does in a final-year engineering lab, making it one of the most consistent investments a student or professional in Bangladesh can make.
Firstly, the number that defines this calculator is 552 functions. That figure covers basic arithmetic, trigonometry, logarithms, complex numbers, matrix calculations, vector operations, statistical analysis, integration, differentiation, equation solving, and a full spreadsheet mode. Additionally, for Bangladesh’s HSC and university students who need to verify textbook results quickly, the natural textbook display shows fractions, roots, and integrals exactly as they appear on the exam paper. Therefore, there is no translation between written work and calculator input — the screen simply mirrors what the student has already written.
However, the feature that surprises most buyers in Bangladesh is the QR code function. After a calculation, you press one button and the FX-991EX generates a QR code. Scan it with any Android or iOS smartphone using the free Casio EDU+ app. The app then shows the full graphical representation of the function — useful for visualising integrals, plotting equation roots, and checking statistical distributions. Consequently, students across Dhaka coaching centres now use this feature to bridge the gap between calculator results and graphical understanding without needing a separate graphing device. According to Casio ClassWiz, the FX-991EX is part of the globally respected ClassWiz series that Casio designed specifically for advanced secondary and tertiary-level education worldwide.
The dual power system removes one of the most common exam anxieties in Bangladesh. Solar cells on the face of the calculator draw energy from classroom light or exam hall fluorescent tubes. A CR2025 lithium battery handles the calculation load when light is insufficient. Therefore, the FX-991EX never fails mid-session because of power — not in a bright Gulshan tutoring centre, not in a dimly lit Narayanganj examination hall, and not in a Rajshahi courtyard coaching session at dusk.
Besides its technical capability, the FX-991EX is a non-programmable scientific calculator. This matters enormously in Bangladesh. SSC, HSC, BUET admission, DU admission, NSU, and most public service commission examinations explicitly permit only non-programmable scientific calculators. The FX-991EX is on the approved list for virtually every examination that allows a scientific calculator in Bangladesh. Therefore, one purchase covers every stage from secondary school through professional certification.
Finally, the build quality justifies the investment. The hard ABS plastic casing absorbs the daily impacts of a student’s bag without cracking. The keys respond with consistent tactile feedback even after thousands of inputs. The high-resolution LCD remains sharp and contrast-rich well into extended night-study sessions. Many engineering students at BUET, RUET, and CUET report using the same FX-991EX through four full years of degree coursework without replacement. At ৳2,300 from eNField-BD with a 1-year manufacturing warranty, the FX-991EX delivers reliable value for every taka invested.

From SSC coaching in Dhanmondi to BUET engineering labs in Dhaka — one calculator handles every stage.
The FX-991EX gives you 552 built-in functions covering every mathematical domain — from basic arithmetic to differential equations and spreadsheets. Moreover, this exceeds the calculation requirements of every Bangladesh examination that permits scientific calculators. Therefore one purchase covers HSC, university entrance, undergraduate, and professional exams for years without limitation.
Scan the QR code with the Casio EDU+ app and see your calculation displayed graphically on your smartphone. Consequently, students can visualise integrals, plot equations, and verify statistical distributions without a separate graphing calculator. Additionally, this bridges the gap between textbook theory and numerical results at virtually no extra cost.
Solar cells charge the FX-991EX from any light source — classroom fluorescents, window light, or exam hall tubes. A CR2025 battery backs up in low light. Therefore the calculator works reliably in every environment across Bangladesh without any mid-session power anxiety during important examinations.
The high-resolution LCD shows fractions, square roots, integrals, and expressions exactly as they appear in Bangladesh’s SSC and HSC textbooks. Consequently, students verify written work directly against the screen without mental format translation. The clear display also remains sharp in low exam-hall lighting across every district.
The FX-991EX is non-programmable, so it is permitted in SSC, HSC, BUET, DU, NSU admissions, and BCS examinations across Bangladesh. Therefore students never need to leave this calculator at home during any exam. Besides, teachers and exam supervisors in Dhaka, Chattogram, and Sylhet recognise it instantly as an approved device.
Casio’s ABS plastic body withstands years of daily use in student bags across Bangladesh’s humid climate. The key mechanism provides consistent tactile response long after other calculators begin to fade or stick. Moreover, many BUET, RUET, and CUET students report using the same FX-991EX throughout a four-year degree without any hardware issue.
