The FX-300ES PLUS family is used for mathematical work that requires more functions than a basic four-function calculator. Its non-graphing design makes it applicable to many classroom, laboratory, homework, and general calculation tasks.

• Arithmetic and fraction calculations
• Middle-school and high-school mathematics
• Algebraic calculations
• Trigonometry
• Scientific notation
• Logarithmic and exponential calculations
• Basic statistical calculations
• Permutations and combinations
• Coordinate conversion
• Table-based mathematical work

Maintenance and Care

Casio specifies cleaning the calculator exterior with a soft, dry cloth. Solvents, abrasive cleaners, and excessive moisture should be avoided because they can damage the housing, markings, display, or internal electronics.

The calculator should not be subjected to excessive impact, bending, pressure, extreme temperatures, high humidity, or heavy dust. When not in use, the supplied hard case can be placed over the front of the calculator to protect the display and keypad.

A dim display can indicate declining battery power. The applicable documentation states that battery replacement should follow Casio’s service guidance, particularly for products sold in the United States and Canada.

Safety Information

The calculator uses a replaceable battery system, so normal battery-handling precautions apply. Casio documentation warns against disassembling, short-circuiting, heating, burning, crushing, or attempting to charge a non-rechargeable battery.

• Use only the specified battery type.
• Install batteries with the positive and negative terminals correctly oriented.
• Do not attempt to recharge a non-rechargeable battery.
• Do not expose the battery to fire or excessive temperatures.
• Do not mechanically crush or cut a battery.
• Replace a depleted battery rather than leaving it installed for an extended period.
• Dispose of the calculator and battery according to applicable local regulations.
• Do not disassemble the calculator.

Technical Specifications

Product History

The FX-300ES PLUS belongs to Casio’s ES PLUS scientific calculator family. Casio subsequently released second-edition versions that retained the Natural Textbook Display approach while continuing the model as a non-programmable, non-graphing scientific calculator.

Casio’s earlier blue FX-300ES PLUS 2nd Edition has been marked discontinued in the company’s United States product catalog. Casio identifies an updated FX-300ES PLUS B 2nd Edition product family as its replacement line.

Packaging and manufacturer part numbers can differ among color, battery, institutional, and distribution configurations. The complete identifier printed on the calculator or packaging should therefore be used when distinguishing closely related versions.

Compatibility

The calculator operates independently and does not require a computer, smartphone, operating system, or software installation. It is intended as a standalone handheld mathematical calculator.

Educational and examination compatibility depends on the rules established by each school, instructor, examination board, or testing program. Being non-programmable and non-graphing does not automatically establish approval for every examination.

Replacement batteries should match the specified AAA battery format. The calculator should not be modified to use an alternative power system.

Frequently Asked Questions

What model is this Casio calculator?

This product is identified by the FX-300ESPLSBBUWAIT distribution and model designation and belongs to the Casio fx-300ES PLUS scientific calculator family.

Is this a graphing calculator?

No. It is designed for scientific calculations without graph plotting or a graphical coordinate display.

Can programs be installed on it?

No. The calculator is non-programmable and does not provide a software installation platform for user-created calculator programs.

Does it display fractions in textbook-style notation?

Yes. Its Natural Textbook Display can present supported fractions, roots, and other mathematical expressions in a layout resembling conventional printed notation.

Can it be used for algebra?

It supports many calculations used in algebra, including powers, roots, fractions, logarithms, scientific notation, and numerical expressions. It is not a computer algebra system and does not perform every symbolic algebra operation.

Permission varies by examination. Users should confirm the exact calculator policy published by the organization administering the test rather than relying only on the calculator’s non-graphing classification.

What are the calculator’s exact dimensions?

Public sources reviewed for this specific distribution configuration provide conflicting measurements. The dimensions are therefore omitted rather than selecting an unverified value.

What warranty applies to this model?

Public product records indicate that warranty coverage exists for products in this category, but a consistent warranty term for this exact distribution configuration was not verified. Current Casio documentation should be consulted for applicable coverage.

Buying Considerations

The first consideration is whether the required mathematics can be performed by a non-graphing scientific calculator. Students who need graph plotting, symbolic algebra, programming, or advanced matrix functionality may require a different calculator category.

Testing rules should also be checked before using the calculator for an examination. Calculator policies can specify allowed model families, restrict programmable equipment, or impose other requirements beyond whether a calculator can graph.

The complete model identifier matters when comparing similar Casio calculators. Several FX-300ES PLUS configurations and revisions exist, and differences can include color, power source, packaging, and distribution part numbers.

Battery maintenance is another practical factor. The battery-powered design avoids reliance on a charging cable, but battery condition should be checked before examinations or other situations where uninterrupted operation is important.

Customer Feedback Summary

This section is reserved for generalized recurring themes from publicly available customer feedback. Customer comments are subjective observations and are not verified product specifications.

At the time of this update, the exact FX-300ESPLSBBUWAIT product record has too little consistent public customer feedback to support a reliable summary of recurring positive and negative themes. Creating generalized claims from a small number of comments could misrepresent broader user experience.

For that reason, no claims about durability, ease of use, classroom performance, battery longevity, or customer satisfaction are presented here as recurring customer feedback. This section can be expanded if a sufficiently broad body of independent public feedback becomes available.
