Understanding the Calculations
The calculator performs two basic mathematical operations:
1. Total Sum Calculation
The total is obtained by adding all entered values together.
Formula
Total=x1+x2+x3+⋯+xn
Where:
- x = each entered value
- n = number of entered values
2. Average Calculation
The average (mean) is calculated by dividing the total sum by the number of entered values.
Formula
Average=nTotal
Where:
- Total = sum of all entered numbers
- n = quantity of values entered
Example Calculation
Let’s assume the following values are entered:
| Row | Values |
|---|---|
| 1 | 10, 20, 30, 40, 50 |
| 2 | 15, 25, 35, 45, 55 |
| 3 | 12, 22, 32, 42, 52 |
| 4 | 18, 28, 38, 48, 58 |
| 5 | 14, 24, 34, 44, 54 |
Step 1: Calculate Total
Total:
10 + 20 + 30 + 40 + 50 +
15 + 25 + 35 + 45 + 55 +
12 + 22 + 32 + 42 + 52 +
18 + 28 + 38 + 48 + 58 +
14 + 24 + 34 + 44 + 54
= 850
Step 2: Count Values
25 values entered
Step 3: Calculate Average
Average = 850 ÷ 25
= 34
Results
| Calculation | Result |
|---|---|
| Total | 850 |
| Average | 34 |

Example
Values:
20, 30, 40, 50, 60
Total:
200
Average:
40
The total shows the combined amount, while the average shows the central value.
