📐 FRACTION PRO — Fraction Calculator & Math Tutor

🔢 BUILT FOR FRACTION ENTRY
• Three separate keypads — whole numbers, numerators, denominators
• No fumbling with a fraction into a normal calculator. Just type it
• Add, subtract, multiply and divide, in seconds
• Handles numbers up to 9 quintillion without overflowing or crashing

🎯 PRECISION CONTROL
• Round to 1/2, 1/4, 1/8, 1/16, 1/32 or 1/64
• Live preview shows how each precision changes your result before you commit
• Round up, down, or to nearest — your call, not the app's

📏 MM TO INCHES
One button. Metric plans, imported hardware, an overseas spec sheet — convert and keep working in fractions.

📊 HISTORY
Every calculation stays on screen in a scrollable list. Check your work from
three cuts ago without redoing it.

📚 SHOW YOUR WORK
Press the 📐 button after any calculation and Fraction Pro explains how it got there — with fraction bars, area models and place value charts, not just an answer.

Traditional Method — the way you learned in school. Step-by-step arithmetic,
conversions and simplification. Free, forever.

Common Core Method — how kids learn it today. Visual models, area diagrams, breaking numbers into parts. Built for parents staring at homework that looks nothing like theirs. Available as an optional one-time purchase.

Both cover addition (common denominators), subtraction (borrowing and
regrouping), multiplication (area models) and division (keep-change-flip), on
whole numbers, fractions, mixed numbers and decimal conversion.

👷 WHO IT'S FOR
• Construction workers — fast, accurate fraction math on the job
• Carpenters — precision rounding that matches your tape
• DIYers — get the measurement right the first time
• Parents — help with homework you don't recognize anymore
• Teachers — show both methods side by side
• Students — understand the why, not just the answer

💡 WHY FRACTION PRO
Most fraction calculators hand you an answer. Fraction Pro shows you the math. Whether you're cutting a 2×4, checking fifth-grade homework, or just adding 3/8 and 5/16 before the saw starts — it's the same app.

🔒 PRIVACY

your device.

Traditional teaching method are free forever. A single one-time purchase
