Pros
- MultiView display shows multiple calculations simultaneously, improving tracking.
- MathPrint displays expressions, symbols, and stacked fractions as they appear in textbooks.
- Includes a root solver, derivatives, integrals, and systems of equations.
- Permitted on the Professional Engineering (FE) exam and most proctored environments.
- Saves calculation history and supports flexible use of three independent stat lists.
- Features built-in constants and unit conversions for physics and chemistry.
Cons
- Buttons can feel "unimpressive" or "mushy" to some users, lacking tactile feedback.
- Chromed keys are difficult to read in certain lighting conditions.
- Defaults to overwrite mode instead of insert when editing expressions, requiring extra steps.
- Lacks a backlit display, making it challenging to use in dim environments.
- Matrix operations are limited to 3x3 matrices.
Dimension Scores
At 5.3 ounces, it's lightweight, but some users report the buttons feel "unimpressive" or "mushy".
As a scientific calculator, it offers no physical adjustability for viewing angle or position.
Many users report long-term durability and use for over a decade, though some find the key feel "unimpressive".
It has a "generic" black design with "aluminium operator keys," and some users dislike the "chromed keys".
Best For
- Students in high school or college math classes where graphing calculators are prohibited.
- Engineering students preparing for or taking the FE exam.
- Anyone needing to perform complex scientific calculations without a full graphing interface.
- Users who benefit from seeing multiple calculations or textbook-style math expressions on screen.
Not Recommended For
- Students requiring advanced graphing functions for higher-level mathematics.
- Users who frequently work with matrices larger than 3x3.
- Individuals needing a backlit display for low-light conditions.
Watch Out For
- The product title's "9.7 Inch" dimension is misleading; the calculator itself is much smaller, with package dimensions closer to 9.76 x 6.77 x 1.1 inches.
- Some users report the chromed keys are "impossible to read in most lighting conditions".
- The calculator defaults to an overwrite function when editing entries, forcing users to manually select "insert" for corrections.
- Battery replacement requires removing screws from the back of the device, which is less convenient than a slide-out tray.

What Buyers Say
What really stands out is how many users praise this calculator for being allowed in exams where graphing models are banned, like the FE exam, making it a go-to for engineering students. People consistently call out the MultiView display and MathPrint for making complex equations easier to handle. However, a recurring complaint is the "unimpressive" feel of the buttons and the difficulty reading the chromed keys in certain lighting. The "9.7 Inch" in the product title is also a common point of confusion, as the calculator itself is much smaller.
“Dude, this calculator got me through my engineering classes and the FE exam, but seriously, those shiny buttons are a pain to read sometimes, and why does it always overwrite instead of insert?!”
Common Praise
- MultiView display shows inputs and results simultaneously, making calculations easier to track.
- MathPrint feature displays fractions and expressions exactly as they appear in textbooks.
- Accepted on most proctored exams, including the FE exam, where graphing calculators are prohibited.
- Handles complex math, statistics, and scientific functions effectively for STEM coursework.
- Saves calculation history and allows for easy copying and pasting.
- Includes a comprehensive library of scientific constants and unit conversions.
Common Complaints
- Buttons can feel "mushy" or lack satisfying tactile feedback.
- Chromed key labels are hard to see in various lighting conditions.
- The default overwrite mode for editing entries is frustrating and inefficient.
- No backlight on the display, making it difficult to read in dim environments.
- Matrix operations are limited to 3x3, which can be restrictive for some advanced users.
Ownership Tips
- The solar panel often keeps the battery charged for years, with many users reporting never needing to replace the CR2013 battery.
- The snap-on lid includes a quick reference guide for functions, which is handy for quick reminders.
- It's surprisingly durable, with some users reporting it still works perfectly after over a decade of use and even surviving drops.
- The calculator's feet on the back help it stay put on a desk, preventing sliding during use.
Frequently Asked Questions
Does this calculator have graphing capabilities?
No, this calculator is specifically designed for curricula and exams where graphing technology is not permitted.
Is the calculator solar powered?
Yes, it is solar-powered, but it also uses a CR2013 coin battery for backup power, which rarely needs changing due to the solar assistance.
Can I use this calculator on standardized tests like the FE exam?
Yes, it is widely accepted on many standardized tests, including the Professional Engineering (FE) exam, because it is non-programmable and non-graphing.
How does the MathPrint feature work?
MathPrint displays mathematical expressions, symbols, and stacked fractions on the screen exactly as they would appear in a textbook, making them easier to read and understand.
What are the limitations for matrix calculations?
The calculator supports matrix operations, but they are limited to a maximum size of 3x3 matrices.
Buying Guide
When you're looking at scientific calculators, especially for school or professional exams, you need to think about what's *allowed* and what features actually help you. This isn't a graphing calculator, which is a huge plus for many tests. Focus on how it displays math (like MathPrint), if it handles the specific functions you need (like integrals or matrices), and how easy it is to use under pressure.
MultiView display
This means the screen can show multiple lines of calculations at once, like seeing your input and the result simultaneously. Think of it like having a small scratchpad right on your calculator screen, instead of just one line.
MathPrint
This feature makes fractions, exponents, and other mathematical expressions look exactly like they do in a textbook. It's like your calculator is printing the math out neatly, which helps prevent errors and makes complex equations easier to understand.
Exam Permitted
This is critical for students and professionals. It means the calculator meets the strict rules of many standardized tests (like the FE exam), allowing you to use it when more advanced, programmable calculators are banned.
Weight (5.3 ounces)
This tells you how light it is. A lighter calculator is easier to carry around in your backpack or briefcase without adding much bulk, which is a small but noticeable convenience for daily use.
Alternatives
If you need a calculator that can graph functions or handle larger data sets for advanced statistics, look for models specifically labeled as "graphing calculators" with a larger display and programming capabilities.
