Integer Math Notice
This calculator is for integer arithmetic and educational use. It rejects decimals and fractions by design. Prime factorization is limited for performance, but core integer operations use exact arithmetic.

How to Use the Integer Calculator
Enter two signed integers A and B. Add an exponent n when you also want A raised to a nonnegative whole-number power.
Review the primary operation cards first, then use the detailed tables for division, GCD, LCM, classification, absolute values, and prime factorization.
Step 1: Enter integer A
Use a positive integer, negative integer, or zero.
Step 2: Enter integer B
B is used for binary operations, division, GCD, and LCM.
Step 3: Set the exponent
The exponent field controls the A^n power result.
Step 4: Compare results
Use the result tables to inspect arithmetic, division, and number properties.
How This Integer Calculator Works
The calculator parses each input as an integer and performs exact signed operations: addition, subtraction, multiplication, quotient, remainder, GCD, LCM, and powers.
Division by a nonzero integer reports a truncated quotient and a programming-style remainder, then separately shows the Euclidean remainder normalized into a nonnegative range.
GCD and LCM use absolute values because divisibility is based on magnitude. LCM returns zero when either input is zero.
Integer Arithmetic Guide
Core Integer Rules
| Concept | Rule | Use |
|---|---|---|
| Integer set | ..., -2, -1, 0, 1, 2, ... | Signed whole numbers without fractions or decimals. |
| Addition | A + B | Combines two integers into an exact integer sum. |
| Subtraction | A - B | Finds a signed difference. |
| Multiplication | A x B | Produces an exact integer product. |
| Quotient and remainder | A = Bq + r | Splits integer division into quotient and remainder when B is nonzero. |
| GCD and LCM | gcd(A,B), lcm(A,B) | Common divisor and common multiple tools for integer arithmetic. |
Examples
| Problem | Result | Notes |
|---|---|---|
| -84 + 30 | -54 | Signed addition. |
| -84 - 30 | -114 | Subtracting a positive integer from a negative integer. |
| 125 / 7 | quotient 17, remainder 6 | Truncated integer division. |
| gcd(-84, 30) | 6 | GCD uses absolute values. |
| lcm(-84, 30) | 420 | LCM is reported as a nonnegative value. |
Integer Context
Integers are closed under addition, subtraction, and multiplication: combining two integers with those operations always gives another integer.
Division is different. An integer divided by another integer may not be an integer, so integer division is usually represented with a quotient and remainder.
