# 4 Best Summation Notation Calculator

Summation Notation Calculator is a mathematical tool that can be used to calculate the summation sigma of a function. These calculators can be used for all types of summations, no matter the length and complexity.

Calculating summations can be a lengthy and confusing task, especially when you are dealing with huge summation problems.

Even if calculating summation is something you are good at, you are still susceptible to making a lot of errors due to the nature of the method.

Summation Notation Calculators can not only help you solve the problems quickly but also with the minimum amount of error.

Summation notation is one of the major breakthroughs in mathematics back in 1755, and it was invented by one the greatest mind in mathematics, Leonhard Euler, who didn’t only invent summation but also invented Pi, imaginary numbers and also logarithmic base e.

Summation notations’ main purpose is to compactly represent the sum of a series of numbers that follow the same trend. It is such an important part of mathematics that you can see the option for summation on conventional scientific calculators as well.

There are a lot of Summation Notation Calculator that you can find online, and it can be a bit overwhelming for individuals who are looking for the best summation notation calculator.

## Best Summation Notation Calculator

1. Good Calculators: Summation Calculator

You might not have heard a lot about Good Calculators, but this website has a decent collection of a lot of practical calculators, including not only maths, but academic calculators, financial calculators, engineering calculators, and a lot more.

They really do live up to their motto, which is “A collection of really good online calculators for use in everyday domestic and commercial use” this website probably has the most practical collection of calculators out there.

The UI of the calculator is quite basic and simple to use, but its design is also really basic, it has no extra design elements or colors.

The fonts used on the calculator are just a little tiny, slightly bigger fonts would have provided a better user experience.

You are required to input 3 entries in the yellow boxes, the upper and lower limit of the summation and your expression in terms of ‘n.’

From a practical standpoint, the design and UI of the website are really good.

You can view all the specific classifications of the calculators you wanna use on the home page and on the left side of the calculator webpage you can see Good Calculators’ top 10 best calculators.

But in general, the look of the website is a bit dull, most of the website uses a grey colour with slight use of blue. The website is well managed and neat but seems a bit outdated and incomplete.

Once you are done with the inputs click, calculate, and your sum will be shown below, and you can also see the steps in the big yellow box below your results.

There is also a button to generate an example if you want to see how the calculators works.

2. Math is Fun: Sigma (Sum) Calculator

As you were already able to tell from its name, Math is Fun is a website all about mathematics. You can find courses, methods and tools related to different fields of mathematics like, Algebra, data, geometry and even physics.

This website isn’t well known but can prove to be very useful and their Summation Notation Calculator is certainly one of the best you can find.

The UI of the calculator is pretty much similar to the one we discussed above, almost all the calculators on this list have the same UI as all of them require the same type of inputs, and give you the same outputs.

Although the design of Math is Fun is kind of ‘fun’ with a little more color and design added to it than the previous one.

Math is Fun has tried to put effort into the design of the website but they certainly weren’t successful in doing that.

The images and icons used on the website are simply not that great, it is website with serious and advanced maths topics, but still the look of the website seems childish and immature.

There aren’t any ads on the website and you won’t run into any errors on glitches on this website.

Once you have the upper limit, lower limit, and summation expression your answer will be displayed below automatically.

The blue box below the inputs will contain all the steps of the summation and you can see the total sum below the blue box.

If you scroll down, you can find some reading material explaining sigma and its functions.

3. GIGA Calculator: Summation Calculator

GIGA Calculator is one of the most popular sites when it comes to calculators, and if you are someone who uses mathematics calculators a lot you probably already know about this website.

They have calculators, randomizers, converters, and articles related to not only maths but also sciences, finance and other everyday stuff. GIGA Calculator’s Summation notation calculator is without a doubt one of the best.

If we talk about the UI of the calculator, it is different from the ones that we have discussed above although most of the inputs are the same as there is only one method for calculating the summation notation.

You have two modes in this calculator make sure you select the ‘Sigma notation (Σ) sum’ at the top of the calculator.

You have to enter 4 inputs in this calculator, the upper limit, lower limit, summation expression and the variable that you are going to use in the expression.

The only thing holding back GIGA Calculator from a great design is the ads on the websites because it has a lot of them. They won’t interfere with your operations of the calculator but still, seem a little distracting.

Once you have entered all the inputs, click calculate, located at the bottom of the calculator and you will get your calculation results, which will contain the total sum and the first 10 numbers of the series.

4. All Math: Summation Calculator

All Math is another website about which you probably haven’t heard that much but they have a range of calculators from a lot of different fields and subjects.

They don’t support a lot of calculators as you can see from their home page that the total amount of calculators that they have are 450.

The UI and design of the calculator are almost like Math is Fun and Good Calculators. Make sure you have selected sigma notation instead of simple notation from the top of the calculator.
