How Many Types of Calculator Are There?

There are five main types of calculator:

  1. Basic
  2. Scientific
  3. Graphing
  4. Printing
  5. Financial

Basic calculators are used by just about everyone to solve common equations, while scientific and graphing calculators are geared towards math students. Printing and financial calculators are a must for those who work with money.

What Are the Different Types of Calculators?

Every calculator can do basic arithmetic, but there are some that are more advanced than others. The different types of calculators are broken down and described below.


Basic Calculators

A basic calculator is sometimes referred to as a 4-function calculator. It’s able to do simple arithmetic, which includes addition, subtraction, multiplication, and division. Use a basic calculator at home to figure out your monthly budget, or when you’re trying to cook a new recipe.

Scientific https://www.mscdirect.com/product/details/02513612

Scientific Calculators

It’s impossible to graduate middle school or high school without a scientific calculator. These calculators are often used by students taking algebra, trigonometry, or geometry. The most commonly purchased brand is Texas Instruments (TI).

Graphing https://www.schoolspecialty.com/texas-instruments-ti-83-plus-battery-power-graphing-calculator-pack-of-10-074052

Graphing Calculators

Graphic calculators are a type of scientific calculator that are also used by students, namely those in college. They’re more advanced and are capable of performing many complex functions such as plotting graphs and completing logarithms.

Printing https://www.amazon.com/Sharp-EL-1801V-Two-Color-Printing-Calculator/dp/B000085BB3

Printing Calculators

If you want a record of your calculations, a printing calculator should be your new best friend! The numbers and figures are printed on a piece of paper that rips off at the top. This old-school calculator is great for those who work with money.

Financial https://www.walmart.com/ip/HP-17bII-Financial-Calculator-22-Digit-LCD/2388775

Financial Calculators

A financial calculator is, as the name suggests, geared towards calculating finances. You can use one to figure out interest rates, mortgage payments, and cash flows. They’re not as common as other types of calculators, but they’re useful for realtors, accountants, and financial advisors.

Online https://www.pinterest.com/pin/86483255314334187/

Online Calculators

Google is capable of pretty amazing things. Simply type in an equation, and the algorithm is usually smart enough to produce an answer. Most laptops and PCs also have a calculator that you can use right on the desktop. If you need a more advanced online calculator, look into websites like Desmos and GeoGabra.


Phone Calculators

Our phones can do it all and that includes math problems! The calculator is a built-in app, like text messaging and email, that comes preprogrammed in all types of smartphones.

Abacus https://www.pinterest.com/pin/29414203793645476/


Can you imagine using beans or stones to do math? Well, that was the method of choice before the abacus was invented in ancient Babylonia! Today, this tool is made from bamboo and beads and is part of many elementary and primary classrooms.

Mechanical https://www.researchgate.net/figure/The-mechanical-calculator-Walther-source-Walther-Calculators_fig1_322506360

Mechanical Calculators

Go for a vintage look by picking up a mechanical calculator, which were all the rage in the 19th century. You might look really weird busting this out to calculate the tip at a restaurant, but at least you’ll be interacting with a piece of history!

Calculators can also be broken down by how they look or how they function. This includes:

Electronic https://www.amazon.com/Mookii-M-25-Calculators-Electronics-Calculator/dp/B073WTYCY9

Electronic Calculators

An electronic calculator is able to solve complex problems. Scientific and graphing calculators fall into this category, using circuit boards and lithium batteries in order to work.

Solar Powered

Solar Powered Calculators

Basic, financial, and printing calculators usually work via solar power. This helps them last for a longer period of time. If your calculator seems to be no longer working, try leaving it outside in direct sunlight!

Touchscreen https://manofmany.com/tech/touchcal-touchscreen-scientific-calculator-brings-calculators-to-the-modern-age

Touchscreen Calculators

A touchscreen calculator works the same as your smartphone. When the battery gets low, it simply needs to be recharged with a USB charger. The world seems to be embracing this type of technology, which could mean even more touchscreen calculators in the future!


Pocket Calculators

Bring your calculations on the go by using a pocket or handheld calculator! The slim, compact design makes it fit with ease in your pocket or in a pencil pouch. Some even have a little latched door that hides the buttons.


Desktop Calculators

Your office will look even more professional with a desktop calculator near your computer. This type of calculator lays flat and has a popped up display screen that shows your calculations. Printing and financial calculators are usually desktop models.

Novelty https://theverybesttop10.com/amazing-calculators/

Novelty Calculators

Show personality by using a novelty calculator! These calculators come in all kinds of unique shapes such as animals, hearts, and even video game controllers. They make excellent gifts for birthdays and holidays!

Is a Calculator Considered a Computer?

Is a Calculator Considered a Computer?

Is a Calculator Considered a Computer?

Many calculators work via electronic circuit boards and utilize data processing. For that reason, there are some who believe that a calculator should be considered a computer.

On the flip side of the argument, the Merriam-Webster dictionary refers to a calculator as “an electronic device” rather than a computer. Techwalla, a popular tech and gadget review site, also released an article noting that “calculators are single-purpose devices,” while computers “have vastly expanded capabilities.”

Whether you think of it as a computer or an electronic device, there’s no denying the power of a calculator! It’s a gadget that belongs in every home, school, or office.

What Words Can You Make With a Calculator?
