## The Best Programmable Calculator – Buyer’s Guide

Programmable calculators are a trademark among **math and science students**. Instead of having to input formulas each time you are calculating a problem. The calculator allows you to store a complicated formula in the form of a program. Before investing in a programmable calculator, here are a few notes to remember.

### Advantages of a Programmable Calculator

**Portable**. These calculators are much easier to carry than a laptop. They offer nearly the same functions as you can find in a computer program with the advantage that you can take the calculator to an exam room. Most of them are lightweight and bear a slim design where they can easily slide in your pocket.

**Offer automated functions**. The most important feature of a programmable calculator is the ability to repeat a step without inputting the whole formula. It comes in handy when you want to input a complex command over and over again by just pressing the ENTER key.

**Allows students to handle complex problems**. Programmable calculators will help you skip the memorization and constant drilling required of math students. Instead, you’ll be able to handle math and science at a much higher level.

### Disadvantages of Programmable Calculators

Even with the help you get from a programmable calculator, there’s still the issue** over-reliance** by students.

### How to Use a Programmable Calculator

**High-level math** is simpler when handled with a programmable calculator. Operating this kind of calculator can be daunting at first, but it is straightforward once you familiarize yourself with the different functions.

Let’s look at how to enter a **program with into the TI-89**:

- To enter a new program, just go to the home screen and hit APPS
- On the menu, open the PROGRAM Editor, go to NEW and Hit ENTER
- On the VARIABLE Box, type a name for the program up to seven letters and HIT ENTER Twice
- Now you can type in each line of the new program

Basic Programming with HP 35s look at the video:

### Programmable Calculator vs. Personal Computer

A programmable calculator and personal computer use **basic computation techniques**. Programmable calculators can store series of formulas and instructions, but that is as far as you can get with this type of calculator. However, a personal computer can interact with the user, run programs, and take user input.

### Programmable Calculator vs. Scientific Calculator

Some scientific calculators are programmable while others are not programmable. For a scientific calculator to be programmable, it has to run on a **Computer Algebra system** (CAS). This system helps to make algebraic functions automatic.

### Programmable Calculator vs. Graphing Calculator

A graphing calculator is simply a scientific calculator with a **graphing function**. These calculators tend to be programmable. They can store, manipulate, and graph functions entered in symbolic form.

They are also **capable of solving** differentiation problems, algebraic expressions, symbolic differentiation, binomial expansion, definite integration, and solve a system of equations.

**Non-programmable calculators** do not come with a function button.

### Commonly Asked Question: Why was a programmable calculator a valuable item in 1976?

Back in 1976, computers were not for everyone. They used to service a lot of people in a building hence it was time-consuming when **waiting your turn** to use one. Manufacturers had already figured out the need for efficiency thus the need to build a calculator that could store programs just like a computer.

Computers were slow since they ran on multiple programs to execute commands. But a programmable calculator had tiny bits of memory and a processor which could implement a few instructions per second. This made them **more attractive** to the busy accountant or scientist who needed to store repetitive calculations for later use.

## Conclusion

**Handheld programmable calculators** have been around for a while now. They allow students and teachers alike to access several stored programs.

We’ve discussed some of the highly sought programmable calculators. They are either scientific or graphing models aimed at fulfilling different purposes. They allow you to solve complex equations **much faster and easier**.

With our selected models, we hope you can choose one that meets **your specific needs **the best.

programmable calculators are best for science and math students. this is the much needed guide for programmable. i am amazed by how well you gave us info about each calculator. thanks

this buyer guide for programmable calculator is best. i am much fascinated by the information that you gave us

This list is incomplete without the Swiss Micros DM42.

Fixed, thanks

“For a scientific calculator to be programmable, it has to run on a Computer Algebra system (CAS). This system helps to make algebraic functions automatic.” This is smiply not true. I have many non-CAS calculators that are programmable: HP-41C, Casio FX-CG50 and on. A CAS allows a calculator to manipulate expressions with uninitialized variables.
