Hi, welcome to our long addition calculator. Long addition is to calculate the sum of two or more than two numbers. Here you can easily and quickly calculate the addition of many numbers. These addends can be integers, decimals, scientific notation, or mix of them.
As we all know, addition is often used in our lives. The addition of 2 numbers is very simple, and the addition of 3 numbers is not difficult, but what if it is the addition of 50 numbers, 100 numbers, or 500 numbers? Or the addends is very large, more than 10 digits or more. Or these addends have both integers and decimals. Can you figure it out easily? To be sure, if you manually calculate it, it will take a lot of time, and the calculated answer may be wrong. In order to get the correct answer, you may have to calculate many times.
Am I right? If so, you have come to the right place. We developed this free online long addition calculator to solve this problem. You don’t need to install new software anymore. Just enter the numbers into the input box, then click calculate, our tool will calculate the answer for you within seconds and ensure that the result is correct.
Of course, if these numbers are consecutive integers, you can use the sum of consecutive integers calculator, which is more convenient than the long addition calculator.
Believe me, this is a very useful tool. Therefore, it is recommended to bookmark this page for next use.At this point, you should have some understanding of the long addition calculator we provide. Are you a little worried about whether this calculator is difficult to use? Does it require other professional knowledge? Don’t worry, our calculator is very easy to use, you don’t need to have other professional knowledge at all, just two or three steps:
Enter the numbers into the input box. The numbers are separated by commas or new lines. Note that the numbers cannot include thousands separators.
Click the “Calculate” button, and the system will immediately give the answer.
If you want to recalculate another numbers, first click the “reset” button, and then repeat steps 1 and 2.
In order to deepen our understanding, let’s give a few examples below. If you want to learn more about the calculation process of addition, please refer to our plus symbol, which has very detailed instructions.
E.g. Add 235, 456, 100, 230
Manual calculation
Use our long addition calculator
So, 235 + 456 + 100 + 230 = 1021.
For example, 1230.25 plus 654.32 plus 15304.12.
By hand calculation
By our long addition calculator
So, addition result of 1230.25, 654.32 and 15304.12 is 17188.69.
For example, get the sum of 230.56, 853.30 and 45011.
By hand calculation
By our long addition calculator
So, the sum of 230.56, 853.30 and 45011 is 46094.86.
Well, with the above content, you should be able to easily use the addition calculator we provide. Here are some common problems:
There are two types, one is by commas, the other is by new lines. For the specific usage, you can check the pictures in the examples above.
In our test, more than 100,000 numbers can be entered. Of course this also depends on the size of each number, so I suggest you try it yourself. A small reminder, if there are many numbers, separate them with commas instead of lines. This can reduce the size of the transmission.
No, just enter the number directly.
Yes, remember to enter the negative sign in front of numbers.
Of course, you can enter negative numbers or scientific notation numbers if necessary.
No problem at all, just like the third example above.
Okay, that’s all about the long addition calculator. If you have any difficulties in using it, please feel free to contact us, and have a good time!
