Basic Calculator Formulas Explained
The Windows 10 Calculator uses standard mathematical formulas for different operations.
Addition Formula
Addition combines two or more numbers.
Formula:
Result = Number 1 + Number 2
Example:
50 + 25 = 75
Subtraction Formula
Subtraction finds the difference between numbers.
Formula:
Result = Number 1 − Number 2
Example:
100 − 40 = 60
Multiplication Formula
Multiplication increases a value by a specific factor.
Formula:
Result = Number 1 × Number 2
Example:
20 × 5 = 100
Division Formula
Division separates a number into equal parts.
Formula:
Result = Number 1 ÷ Number 2
Example:
100 ÷ 4 = 25
Percentage Formula
Percentage calculations determine a portion of a total value.
Formula:
Percentage Value = (Percentage ÷ 100) × Total Number
Example:
Calculate 20% of 500:
(20 ÷ 100) × 500
= 100
Windows 10 Calculator Example Calculations
Understanding examples can make calculator usage easier.
Example 1: Addition Calculation
Suppose you purchased:
- Item A: $45
- Item B: $35
Total cost:
45 + 35 = 80
The calculator gives:
Total = $80
Example 2: Discount Percentage Calculation
A product costs $200 and has a 15% discount.
Discount amount:
(15 ÷ 100) × 200
= 30
Final price:
200 − 30 = 170
The calculator helps complete these steps quickly.
Example 3: Multiplication Calculation
A business orders 25 boxes with 12 items in each box.
Calculation:
25 × 12 = 300
Total items:
300
