One Step Inequalities Calculator
📌 What Is a One-Step Inequality?
A one-step inequality is a basic algebraic expression involving a variable, a constant, and an inequality operator (like >, <, ≥, or ≤), which can be solved using a single mathematical operation such as addition, subtraction, multiplication, or division.
Example:
If you have:
2x > 6
The one step to solve it is dividing both sides by 2:
x > 3

🔧 How to Use the Inequality Calculator
Using the One-Step Inequality Calculator is incredibly straightforward. Here’s a quick step-by-step guide:
1. Enter the Coefficient
This is the number multiplied by the variable. For example, in 3x > 9, the coefficient is 3.
2. Enter the Variable
Typically “x”, but you can input any single character (like y or z).
3. Select the Operator
Choose from:
- Greater than (>)
- Greater than or equal to (≥)
- Less than (<)
- Less than or equal to (≤)
4. Enter the Constant
This is the number on the other side of the inequality sign.
5. Click “Calculate”
The tool instantly displays the solution based on your inputs. If any invalid entries are detected, you’ll receive a prompt to correct them.
6. Click “Reset” to Start Over
Clear all fields and try a new inequality with one click.
🧪 Example Calculation
Let’s solve a simple inequality using the tool:
Input:
- Coefficient: -2
- Variable: x
- Operator: >
- Constant: 6
Manual Steps:
To solve: -2x > 6
Divide both sides by -2, remembering to flip the inequality sign:
x < -3
Result Shown by Calculator:
x < -3.00
This tool does all the work, including flipping the sign when dividing by a negative coefficient—something even experienced students often forget.

📚 20 Most Frequently Asked Questions (FAQs)
1. What is a one-step inequality?
A one-step inequality can be solved using just one operation like addition, subtraction, multiplication, or division.
2. Why does the inequality sign flip when dividing by a negative?
In mathematics, dividing both sides of an inequality by a negative number reverses the inequality to preserve its truth.
3. Can I use letters other than “x”?
Yes, the calculator accepts any single-character variable (e.g., y, z, a).
4. What happens if I leave the variable field blank?
The calculator defaults to “x” as the variable.
5. What operators are supported?
Greater than (>), less than (<), greater than or equal to (≥), and less than or equal to (≤).
6. Does the calculator support two-step inequalities?
No, this calculator is specifically for one-step inequalities.
7. Is there a limit to how large the numbers can be?
No, you can enter very large or small numbers, including decimals.
8. Can I use decimal values?
Yes, decimals are supported for both coefficients and constants.
9. Does it work with negative numbers?
Absolutely! It even adjusts the inequality direction when needed.
10. What if I enter a coefficient of 0?
The calculator will alert you that a zero coefficient is invalid (as it removes the variable).
11. Can this help me with math homework?
Yes! It’s an ideal tool for quickly checking your work or understanding the process.
12. Is the result rounded?
Yes, results are rounded to two decimal places for clarity.
13. Do I need an internet connection?
Yes, this tool is web-based and needs internet access to function.
