A calculator is said to be a small electronic device that performs both involved and mathematical arithmetic operations. It’s also referred to as a machine that makes math operations easy to solve. These tasks are addition, subtraction, multiplication, and division. The advanced math calculators can do square roots, draw functions and can help in calculus. A computer or a smartphone is also known to be a calculator. A calculation calculator contributes to tackling mathematical problems.

**Types of Math Calculators**

Math calculators are found all over the internet and outside in the real world varying regarding cost. It’s crucial to know which math calculator you need to perform a certain job. There are three most common calculators;

__Handheld calculators__:

Handheld calculators are the most basic calculator found in the world today. It’s simple to handle, pocket-sized, powered by the solar and used for basic mathematics only. The calculators come in attractive colors, designs and are often stylish. Basic calculators contain fewer functions and display results in just a line. The calculators are known as four function calculators since they do perform only addition, subtraction, multiplication and division only. We do have other calculators that can do basic functions such as tax, calculations and discount amounts. Handheld calculators can also copy values between the sub-display and the primary display, or independent actions can take place simultaneously.

__Printing calculators:__

These calculators were used a long time before computers were created to run all the total numbers over a particular period. They feed off a role of tape to provide a record of the calculations made. They can print in two colors mainly black and red to represent positive and negative values form of identification. They are fast and known to keep up with most experienced Integer cruncher. Printing calculators are large; they are quick, and their display is better than the handheld calculators.

__Scientific calculators__

They are calculators that offer a broad range of conversions, analysis, statistics and data plotting. The calculators are the most advanced calculators and provide a variety of functions to solve mathematical problems. Most scientific calculators used the VPAM method, a kind of notation for various algebraic functions. The calculator contains quite some math functions that offer mathematicians the ability to tackle complex tasks like fraction calculations, permutations, and combinations. They have some of the features listed below;

- Dot-matrix display with a high-resolution screen that allows graphs and numbers to be spotted clearly.
- 2-digit and 10-digit mantissa exponential display
- A sophisticated memory that is quick and easily recalls previously done calculations
- Re-execution and editing of formula
- Editing of data input and back viewing.

Before the creation of math calculators, math was done using pencil, mind, and paper. The four function calculator has by time evolved to be a readily available calculator that meets our needs. They are those powerful calculators that feel the industry and academic needs which do different functions from a core and ordinary calculators. These advanced calculators can be programmed, and some have print out features.
