Windows 10 Calculator Formula Explanation
Although the calculator performs calculations automatically, understanding the formulas behind each operation helps users understand how results are generated.
Addition Formula
Addition combines two or more values.
Formula:
Result = Number 1 + Number 2
Example:
40 + 60 = 100
Subtraction Formula
Subtraction finds the difference between two values.
Formula:
Result = Number 1 – Number 2
Example:
100 – 45 = 55
Multiplication Formula
Multiplication calculates repeated addition.
Formula:
Result = Number 1 × Number 2
Example:
25 × 4 = 100
Division Formula
Division separates one number into equal parts.
Formula:
Result = Number 1 ÷ Number 2
Example:
200 ÷ 5 = 40
Percentage Formula
Percentage calculations convert a value into a fraction of 100.
Formula:
Percentage Value = Number ÷ 100
Example:
20% = 20 ÷ 100 = 0.20
To calculate 20% of 500:
500 × 0.20 = 100
Practical Examples Using Windows 10 Calculator
Example 1: Monthly Expense Calculation
Suppose your monthly expenses are:
- Rent: $800
- Food: $300
- Transportation: $100
Using addition:
800 + 300 + 100 = 1200
Your total monthly expense is:
$1,200
Example 2: Discount Calculation
A laptop costs $900 and has a 10% discount.
First calculate the discount:
900 × 10% = 90
Subtract:
900 – 90 = 810
Final price:
$810
Example 3: Splitting a Restaurant Bill
A restaurant bill is $150 and four people share equally.
Calculation:
150 ÷ 4 = 37.50
Each person pays:
$37.50
