Calculation Examples

Basic Arithmetic

Perform everyday calculations quickly and accurately.

Examples

• 125 + 75 = 200
• 450 − 128 = 322
• 25 × 16 = 400
• 144 ÷ 12 = 12

Calculate Powers

Use the power (xʸ or ^) function to raise a number to an exponent.

Examples

• 5² = 25
• 3⁴ = 81
• 10³ = 1,000

Powers are commonly used in algebra, engineering, and scientific formulas.

Find Square Roots

Use the square root (√) function to calculate the square root of a number.

Examples

• √64 = 8
• √225 = 15
• √2 ≈ 1.414

Square roots are frequently used in geometry, algebra, and physics.

Calculate Trigonometric Functions

The calculator includes the three primary trigonometric functions:

• Sine (sin)
• Cosine (cos)
• Tangent (tan)

Examples (Degrees)

• sin(30°) = 0.5
• cos(60°) = 0.5
• tan(45°) = 1

Before calculating, make sure the calculator is set to Degrees (DEG) or Radians (RAD) depending on your problem.

Calculate Logarithms

Logarithms are widely used in mathematics, science, and engineering.

Examples

• log(100) = 2
• log(1000) = 3
• ln(e) = 1

The log function calculates the base-10 logarithm, while ln calculates the natural logarithm (base e).

Calculate Exponents

Use exponents for compound growth, scientific notation, and advanced equations.

Examples

• 2⁸ = 256
• 7⁵ = 16,807
• e² ≈ 7.389

Use Mathematical Constants

Pi (π)

Pi is commonly used for calculations involving circles and trigonometry.

Example

Circumference of a circle with a radius of 10:

2 × π × 10 ≈ 62.83

Euler's Number (e)

Euler's Number is used in calculus, exponential growth, finance, and probability.

Example

e³ ≈ 20.086

Calculate Percentages

The calculator can also be used for percentage calculations.

Examples

• 20% of 250 = 50
• 15% of 80 = 12
• 250 + 15% = 287.5

Useful for discounts, tax, interest, and financial calculations.

Use Parentheses

Parentheses control the order in which calculations are performed.

Example

Without parentheses:

5 + 3 × 4 = 17

With parentheses:

(5 + 3) × 4 = 32

Using parentheses ensures calculations are evaluated correctly.

Solve Complex Expressions

The calculator can evaluate multiple operations in one expression.

Example

((15 × 8) + √144) ÷ 6

Step by step:

• 15 × 8 = 120
• √144 = 12
• 120 + 12 = 132
• 132 ÷ 6 = 22

Common Uses

The Scientific Calculator is commonly used for:

• Mathematics homework
• Algebra and geometry
• Trigonometry
• Calculus
• Physics calculations
• Chemistry equations
• Engineering formulas
• Computer science
• Statistics
• Financial calculations
• Technical problem solving
• Classroom learning

Tips for Better Results

• Check whether your calculation requires Degrees (DEG) or Radians (RAD) before using trigonometric functions.
• Use parentheses for complex equations to ensure the correct order of operations.
• Double-check your numbers before calculating.
• For long expressions, review each operator carefully to avoid typing mistakes.
• Use the built-in constants such as π and e instead of manually entering approximate values for greater accuracy.
