This Sum Calculator helps you find the sum of a list of numbers and shows each step clearly. It works by listing the values, writing the addition expression, and then adding all the values together to get the total. This makes it useful for checking answers, understanding how totals are calculated, and practising statistics step by step.

Step-by-step method

Add all the values together to get the total sum.

Formula:

\(S = \Sigma x\)

Example 1: Take the values below.

\(1,\; 2,\; 3,\; 4,\; 5\)

Step 1 - Add all the values together to get the total sum.

In this problem: Add the values: \(\Sigma x = 1 + 2 + 3 + 4 + 5 = 15\).

\(\Sigma x = 1 + 2 + 3 + 4 + 5 = 15\)

Final answer:

\(S = 15\)

Example 2: Take the values below.

\(3,\; 10,\; 23,\; 12\)

Step 1 - Add all the values together to get the total sum.

In this problem: Add the values: \(\Sigma x = 3 + 10 + 23 + 12 = 48\).

\(\Sigma x = 3 + 10 + 23 + 12 = 48\)

Final answer:

\(S = 48\)
