Equation Solver and Step by Step Explainer

📝 Description

The Universal Math Solver is a fully client-side web application designed to support students, parents, and teachers with real-time, step-by-step solutions to a wide range of math problems aligned with modern curricula (Common Core, IB PYP/MYP, Cambridge, and more).

✅ What It Solves:

Primary (Gr 1–5): Basic arithmetic, simple word problems

Middle School (Gr 6–8):

Fraction and decimal rates (e.g., "3/4 kg costs $6. How much for 2 kg?")

Unit conversions (kg ↔ g, m ↔ cm, L ↔ mL)

Multi-step word problems (e.g., "Buys 2 kg at $4/kg. Pays $20. How much change?")

Percentages, ratios, geometry (area, perimeter), and basic statistics

🔒 Safe & Private:

No internet required after loading

No data collection — all calculations happen in your browser

No ads during problem-solving — clean, distraction-free learning

💡 Designed for Understanding:

Every solution includes clear, teacher-style explanations that build conceptual understanding — so you learn while you solve.

Select your problem

Type your math question in natural language, just like you’d say it:

→ "3/4 kg costs $6. How much for 2 kg?"

→ "Convert 2.5 kg to g"

→ "Sarah buys 2 kg apples at $4/kg. She pays with $20. How much change?"

Click “Solve”

The solver analyzes your input, identifies the math concept, and generates a step-by-step breakdown.

Learn from the steps

Read each step to understand the reasoning. The final answer is clearly highlighted.

❓ Frequently Asked Questions (FAQ)

Q: Do I need an internet connection to use this?

A: Only to load the page the first time. After that, everything works offline — perfect for classrooms or areas with limited connectivity.

Q: Is this safe for kids?

A: Absolutely. There are no external trackers, no data collection, and no third-party content during problem-solving. (Ads appear only in designated zones and comply with child-safe policies when deployed.)

Q: Why doesn’t it solve my problem?

A: The solver understands clear, complete sentences with numbers and units. Try rephrasing like:

❌ "apples cost money" → ✅ "3 apples cost $1.50. How much for 10?"

❌ "change money" → ✅ "Buys 2 kg at $4/kg. Pays $20. How much change?"

Q: Can it handle fractions like 2½ or 3/4?

A: Yes! Use 3/4 for fractions. Mixed numbers like 2 1/2 should be written as 2.5 or 5/2.

Q: Does it show work for geometry formulas?

A: Yes! For example, input "Area of rectangle 5 by 8" and it will show:

Area = length × width = 5 × 8 = 40

Q: Can I use this on my phone?

A: Yes! The app is fully responsive and works on phones, tablets, and desktops.

Q: Is this free?

A: Yes — and it always will be. It’s built for education, not profit.
