# The Best Non Graphing Calculator

## Professor won't let you use a graphing calculator? Here's our roundup of 5 scientific calculators that will help you get through class.

You’ll need a calculator you can bring with you to classes, work, or your next big test. During special engineering tasks, standardized testing, or ordinary classes, the right calculator is a must.

## Types of Calculators

Before you choose a non-graphing calculator, it’s important to understand what sets them apart. Basic calculators are only capable of division, multiplication, addition, and subtraction. While some models can also calculate percentages and square roots, they tend to have limited functionality outside of that.

One benefit to a typical, basic calculator is simplicity. You won’t have to struggle to use one of these tools. Graphing calculators are for people who must program customized functionalities into the calculator. They’re also useful for plotting points on a graph.

People who are taking calculus, geometry, or majoring in engineering use these calculators. Note that these tools cost significantly more than non-graphing models. Non-graphing calculators (also called scientific calculators) are for more advanced math problems. If you’re about to start a physics, chemistry, or trigonometry class, you’ll need one.

Now that you have a basic understanding of the most common types of calculators out there, it’s time to choose a non-graphing calculator. Below, we’ve selected a few different models for different needs.

Most users will notice that it’s simple to use for calculating angle unites in trigonometry and performing fractional equations. The calculator shows stacked fractions, symbols, and math expressions the way they appear in textbooks. You can see multiple calculations displayed on the screen at once.

You may choose between three solvers: system of linear equations, polynomial, and numeric equation. The buttons are made with hard plastic and color-coded for your convenience.

#### Pros

- Comes with a sliding protective case
- Shuts off automatically
- Color-coded keys
- Affordable price
- Lightweight design

#### Cons

- Doesn’t have full complex number support

- and compact
- Attractive design
- Solar and battery power

#### Cons

- May not last as long as more expensive models

#### Best for Calculus Students

### The Casio FX-115ES

The Casio FX-115ES has been designed to be user-friendly regardless of your level of knowledge. It has enhanced features such as finding derivatives, advanced inequality functionality, and product notation templates. The Casio FX-115ES does matrix inversion, quadratics, and cubics.

It’s super easy to use and has an affordable price. If you’re taking Pre-Calculus, Trigonometry, Statistics, Pre-Algebra or Algebra I or II, General Math, Chemistry, Engineering, or Physics, this tool will support you. It may be used on NCEES exams, AP tests, ACT, SAT, PSAT, and NMSQT tests. The tool comes with battery backup and solar power, so you can use it no matter what. Its functions are intuitive and it has a natural textbook display for easy reading.

## Conclusion

Unless you require one for a very specific purpose, you don’t need to spend a ton on a graphing calculator. Instead, choose a non-graphing (scientific) calculator like one of the options on our list.

The HP 35s Scientific Calculator is our favorite overall due to value for the price and the functions it offers. Maybe you’re a bit intimidated by RPN (although the 35s supports algebraic notation as well. Here’s a good video that explains the HP 35s RPN system.

Non-graphing calculators are in high demand for engineers and students who need to take certification tests that restrict other calculators. They’re useful for physics, trigonometry, and other studies, as well.

Hopefully, this article helped you select the best one for your needs.

## Frequently Asked Questions

### What is the difference between a CAS graphing calculator and a non-CAS graphing calculator?

A non-CAS calculator solves for numeric results whereas a CAS calculator can give you algebraic answers – integrals, derivatives, simplify equations.

### What is the best non-graphing calculator?

That depends on your needs, but the HP 35s is a solid choice. If you’re on a budget then check out the Ti-36x Pro from Texas Instruments.

### What is a non-programmable calculator?

A simple numeric calculator without macros or programming functions. Used for basic math calculations like addition, subtraction, multiplication, division, square root etc.

### What is RPN?

RPN stands for Reverse Polish Notation. It is an alternate mathematical notation where the operands are entered before the operators (multiplication, division etc.). Some calculators (particular HP) use this method.
