If you’re entering middle school, or high school, and you’ve been told you need to get a scientific calculator for your math classes, you might be freaking out about now. All those buttons, and functions, and things you can’t identify are kind of overwhelming. We’ve pulled together information to help you not only better understand using a scientific calculator, but to help you find the best scientific calculator for your needs, as well.

First, let’s start with an understanding of what a calculator is, and why they came into existence.

## A Short History of the Calculator

The long history of the calculator can be traced back to the abacus, a hand operated counting machine that uses beads on rods. This device was first employed by the Egyptians and Sumerians around 2000 BCE. This revolutionary tool sped up the counting and subtracting process by using multiple rows of beads to represent tens, hundreds, thousands, and so on. This concept was so effective that people found no need for the technology to change from nearly 3,600 years.

The next development towards the modern calculator came about in the 17th century AD. This development was called the slide ruler. The slide ruler is a sliding stick that uses logarithmic scales to allow the user to do rapid multiplication and division. Later developments with the slide rule allowed for its use in square roots, exponents, logarithms, and trigonometry. The first calculator that made use of mechanical function was created in 1642. This device was invented by French mathematician Blaise Pascal. This machine utilized geared wheels, and could add and subtract two numbers by direct input. By the utilization of repetition, the machine could be used to multiply and divide, as well.

The next innovation in calculating machines was that of a four-function device. This invention came about in 1820: Thomas de Colmar’s Arithmometer. The first commercially viable counting device would not be manufactured until 1851. The next great innovation in calculating machines came about in 1887, when Dorr E. Felt made a calculating device that could be operated by push buttons. Next, electronic calculators began their life in the 1930s, as the world faced the impending likelihood of another war. Two war time needs really drove the development of an electronic computing device. The first need was making the use of anti-aircraft and bombers more effective. The second reason was the growing challenge of code breaking. These needs led to the first all-electronic computer called Colossus.

Then, in 1948, a pocket-sized version of the mechanical calculator was released. This new machine was called the Curta Calculator. The world’s first completely electronic desktop calculator was released in 1961. This device was called ANITA, which stood for A New Inspiration To Arithmetic/Accounting. The calculator used push button key technology mixed with vacuum and cold cathode tubes. For three years this sold without competition until transistor driven calculators appeared. At this point, numerous companies around the world released a series of transistor driven calculators. Innovations came from different companies in different countries. Toshiba, for example, created the Toscal BC-1411 which utilized an early form of RAM.  From the Italian manufacturer, the Programma 101 could read and write to magnetic cards and used a built in printer to display computations.

These innovations led up to a company called Texas instruments releasing a landmark device in 1967. This device was called the Cal Tech. This was a calculator that could do a multitude of functions while being compact enough to be hand held.

## Types of Calculators

There are a number of calculator types.

• Financial
• Graphing
• Scientific

There are, of course, also a variety of online calculators with specific functions, such as pregnancy, BMI, water, and calorie calculators. Each of these specifically functional calculators meet very specific needs with algorithms programmed into them to find the correct results. While all types of calculators can serve incredibly important functions, today, we’re focusing on scientific calculators.

## What is a Scientific Calculator?

Scientific calculators are hand-held calculators which are designed for aiding in solving problems in mathematics, science, and engineering. Commonly, most people are first exposed to these types of calculators in middle and high school, while taking various mathematics courses.

Defining features commonly found in scientific calculators include:

• Logarithmic functions
• Trigonometric functions
• Scientific Notation
• Floating Point Arithmetic
• Roots and Exponential Functions beyond the square root
• Fraction Calculations
• Calculus
• Unit Conversion

They are designed for use in various math types such as:

• Pre-Algebra
• Algebra 1 and 2
• Statistics
• Physics
• Geometry
• Trigonometry

## How to Use a Scientific Calculator

When taking higher level mathematics, students will find that a scientific calculator becomes an important tool for time efficiency. However, if you have previously only used a standard, or “normal” calculator, you may feel a little intimidated by the various buttons and functions on a scientific calculator. For help with overcoming this intimidation, you can look online for help. A tutorial, or step-by-step manual would offer ways for you to become better acquainted with, and proficient with your scientific calculator.
