Formula Explanation Behind Common Calculations
Although the calculator automatically performs calculations, understanding the basic formulas helps users verify results.
Addition Formula
Addition combines two or more numbers.
Formula:
Result = Number 1 + Number 2
Example:
45 + 35 = 80
Subtraction Formula
Subtraction finds the difference between numbers.
Formula:
Result = Number 1 − Number 2
Example:
100 − 40 = 60
Multiplication Formula
Multiplication represents repeated addition.
Formula:
Result = Number 1 × Number 2
Example:
25 × 8 = 200
Division Formula
Division separates a number into equal parts.
Formula:
Result = Number 1 ÷ Number 2
Example:
100 ÷ 5 = 20
Percentage Formula
Percentage calculations determine a portion of a total amount.
Formula:
Percentage = (Part ÷ Total) × 100
Example:
A product costs $500 and has a $50 discount.
Discount percentage:
(50 ÷ 500) × 100
= 10%
Practical Examples Using the Windows 10 Missing Calculator
Example 1: Monthly Expense Calculation
Suppose you spend:
- Food: $350

The calculator quickly provides the total monthly spending.
Example 2: Shopping Discount Calculation
A jacket costs $80 and has a 25% discount.
Calculation:
80 × 25%
80 × 25 ÷ 100
Discount:
$20
Final price:
80 − 20
= $60
Example 3: Business Profit Calculation
A business purchases products for $1,500 and sells them for $2,000.
Profit:
2,000 − 1,500
= $500
Profit percentage:
(500 ÷ 1500) × 100
= 33.33%
