Inverse Operations Calculator
Understanding inverse operations is a fundamental part of mathematics. Whether you're solving algebra equations, checking exponent rules, or verifying trigonometric values, inverse operations help you confirm your answers quickly and accurately.
Our Inverse Operations Calculator allows you to compute and verify:
- Addition ↔ Subtraction
- Multiplication ↔ Division
- Exponents ↔ Roots
- Exponentials ↔ Logarithms
- Trigonometric ↔ Inverse Trigonometric Functions
It not only calculates the result but also shows the inverse operation and verification step — making it perfect for students, teachers, and anyone reviewing math concepts.
What Are Inverse Operations?
Inverse operations are operations that undo each other.
For example:
- Addition is undone by subtraction
- Multiplication is undone by division
- Exponents are undone by roots
- Logarithms undo exponentials
- Sine is undone by arcsine
They are essential in solving equations and verifying results.
1. Addition and Subtraction
4
Example:
If:
5 + 3 = 8
Inverse operation:
8 − 3 = 5
The subtraction verifies the original addition.
This is commonly used in algebra to isolate variables.
2. Multiplication and Division
4
Example:
6 × 4 = 24
Inverse operation:
24 ÷ 4 = 6
Division reverses multiplication and confirms accuracy.
Important note: Division by zero is undefined.
3. Exponents and Roots
4
Example:
2³ = 8
Inverse operation:
³√8 = 2
Taking the nth root reverses exponentiation.
This concept is heavily used in algebra and calculus.
4. Exponentials and Logarithms
4
Logarithms are the inverse of exponential functions.
Example:
10² = 100
Inverse operation:
log₁₀(100) = 2
The calculator allows you to choose any base (except 1).
Rules:
- Base must be positive
- Base cannot equal 1
- Value must be positive
5. Trigonometric and Inverse Trigonometric Functions
4
Trigonometric functions use angles, while inverse trig functions return angles.
Example:
sin(30°) = 0.5
Inverse:
arcsin(0.5) = 30°
The calculator converts degrees to radians internally and verifies the result.
Functions supported:
- Sine (sin) ↔ arcsin
- Cosine (cos) ↔ arccos
- Tangent (tan) ↔ arctan

Logarithms and exponentials, in particular, are heavily used in science and engineering.
Common Mistakes to Avoid
- Dividing by zero
- Using log base 1 (undefined)
- Forgetting angle units (degrees vs radians)
- Ignoring negative root cases
- Rounding too early
This calculator helps prevent those mistakes by validating inputs automatically.
