Mathematical Formulas Used

The calculator performs calculations based on standard arithmetic formulas.

Addition Formula

$Result = X + Y$ Result=X+Y

Example:

$10 + 5 = 15$ 10+5=15

Subtraction Formula

$Result = X – Y$ Result=X−Y

Example:

$10 – 5 = 5$ 10−5=5

Multiplication Formula

$Result = X \times Y$ Result=X×Y

Example:

$10 \times 5 = 50$ 10×5=50

Division Formula

$Result = \frac{X}{Y}$ Result=YX

Example:

$10 \div 5 = 2$ 10÷5=2

Power Formula

$Result = X^Y$ Result=XY

Example:

$2^3 = 8$ 23=8

Understanding Each Operation

Addition

Addition combines two numbers into one total value.

Common Uses:

Budget calculations
Shopping totals
Score tracking
Financial planning

Example:

If your monthly income is $2,000 and your side income is $500: $2000 + 500 = 2500$ 2000+500=2500

Total income = $2,500

Subtraction

Subtraction finds the difference between two values.

Common Uses:

Expense tracking
Profit calculations
Distance measurement
Inventory management

Example:

If you had $1,000 and spent $250: $1000 – 250 = 750$ 1000−250=750

Remaining balance = $750

Multiplication

Multiplication calculates repeated addition.

Common Uses:

Product pricing
Area calculations
Salary estimates
Data analysis

Example:

If one item costs $20 and you buy 6 items: $20 \times 6 = 120$ 20×6=120

Total cost = $120

Division

Division splits a value into equal parts.

Common Uses:

Average calculations
Expense sharing
Unit pricing
Performance metrics

Example:

If 100 candies are divided among 5 children: $100 \div 5 = 20$ 100÷5=20

Each child gets 20 candies.

Power (Exponentiation)

Power calculations raise a number to an exponent.

Common Uses:

Scientific calculations
Compound growth
Engineering formulas
Computer algorithms

Example:

$3^4 = 81$ 34=81

Meaning: $3 \times 3 \times 3 \times 3 = 81$ 3×3×3×3=81
