What you are paying for: a quick spec comparison

Casio splits its non-programmable scientific calculators into the older MS series and the newer ES Plus / EX (ClassWiz) series. The headline difference is the display: MS models use a simpler two-line display, while ES Plus and EX models use a Natural Textbook Display that shows fractions, roots and integrals the same way they appear in a printed textbook.

Casio FX991ES Plus 2nd Edition

This is the model most A/L science students and undergraduates reach for. Casio lists the FX991ES Plus with 417 functions and a 10 + 2 digit Natural Textbook (dot-matrix) display, with 9 memory variables for storing intermediate results (Casio official product page). It is solar-and-battery powered with an approximate main battery life of 3 years, measures 161.5 × 77 × 11.1 mm and weighs only 95 g, and ships with a slide-on hard case.

• Equation, matrix, vector and complex-number calculations
• Integration and differential calculus support
• Statistics, standard deviation and regression analysis
• Base-n calculations and conversions

Casio FX991MS

The FX991MS is the value pick at Rs 5,800. It is solar-and-battery powered, carries the same 9 variable memories, and handles fractions, equations, integration/differentiation, matrix and vector work, plus access to 40 scientific constants. It uses the two-line MS display rather than the natural textbook view, which keeps the price lower while covering everything an A/L maths or physics syllabus requires.

Casio FX100MS

At Rs 5,600, the FX100MS is the most affordable model on the list. It offers 300 functions, a dot-matrix 2-line display with 10 + 2 digits, 9 variable memories, and measures 16.2 × 7.7 × 1.4 cm. It is battery-powered (AA-size) and includes a slide-on hard case, making it a dependable, budget-friendly choice for school students.

Why Casio dominates the calculator aisle

Scientific calculators remain a steady, growing global category rather than a fading one, kept alive by STEM education and exam requirements. Market analysts continue to forecast healthy single-digit annual growth for the segment.

“The Global Scientific Calculator market is Growing at Compound Annual Growth Rate (CAGR) of 5.80% from 2023 to 2030.”

That sustained demand is one reason Casio’s non-programmable models are accepted in most local and international exam halls: they are reliable, affordable, and standardised. For Sri Lankan buyers, the practical takeaway is that a genuine Casio holds its usefulness for years, especially given the roughly 3-year battery life on the ES Plus series.

How to choose the right model

• School / O-Level student on a budget: the FX100MS (Rs 5,600) covers the curriculum at the lowest price.
• A/L science or maths student: the FX991MS (Rs 5,800) or FX991ES Plus 2nd Edition (Rs 6,800) for the textbook-style display.
• Undergraduate / engineering professional: the FX991EX ClassWiz (Rs 9,800) for the fastest processor and high-resolution display.
• Schools or businesses buying in bulk: ask about wholesale pricing, such as the FX991ES Plus 2nd Edition at Rs 6,500.

Where to buy in Sri Lanka
