Sum Calculator
This Sum Calculator adds a list of numbers into one total and shows the working line by line. The values are added in the order they were entered, so the running total can be followed and checked against your own. Negative values subtract as they are reached rather than needing separate handling. This total is also the first thing the mean and the average need. Following the same pattern every time makes a long addition easy to check and repeat.
Step-by-step method
- Set up the problem.
- Write the formula.
- Add the values together to get the total.

- Add the values together to get the total.
Step 1
Step 1 - Set up the problem.
In this problem: We are adding the \(4\) values \(5,\; 8,\; 12,\; 15\) together.
Step 2
Step 2 - Write the formula.
In this problem: The total is what every value adds up to, written as the sum of all the values.
Step 3
Step 3 - Add the values together to get the total.
In this problem: Adding them in order gives \(5 + 8 + 12 + 15 = 40\).
