📏 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.
