Word Problem Solver Form
Choose a structured problem type, enter the known values, and solve the missing quantity with steps, exports, and a chart.
Example Data Table
| Problem Type | Sample Inputs | Expected Output |
|---|---|---|
| Rate, Time and Distance | Rate = 60 km/h, Time = 3 h | Distance = 180 km |
| Percent Change | Original = 250, Increase = 20% | Final Value = 300 |
| Simple Interest | Principal = 5000, Rate = 6%, Time = 2 years | Interest = 600, Amount = 5600 |
| Work Rate | A = 6 h, B = 8 h, Jobs = 1 | Together Time ≈ 3.43 h |
| Mixture | 3 L at 20%, 5 L at 40% | Final Concentration = 32.50% |
| Age Problem | Younger = 12, Difference = 4, Years Ahead = 6 | Older = 16, Future Ratio = 1.22 |
Formula Used
Rate, Time and Distance: D = R × T, R = D ÷ T, T = D ÷ R
Percent Change: Final = Original × (1 ± p/100), p = ((Final − Original) ÷ Original) × 100
Simple Interest: I = (P × R × T) ÷ 100, A = P + I
Work Rate: 1/Together Time = 1/A Time + 1/B Time
Mixture: Final Concentration = (V1 × C1 + V2 × C2) ÷ (V1 + V2)
Age Problems: Older Age = Younger Age + Difference, Future Ratio = (Older + n) ÷ (Younger + n)

FAQs
1. What does this word problem solver calculator do?
It solves common math word problems using structured templates. You choose the problem type, enter known values, and the page returns formulas, steps, a result table, exports, and a graph.
2. Does it understand every sentence automatically?
No. It works best when you first identify the matching category, such as distance, percent change, work, or mixture. The optional text box helps you store the original statement with the solution.
3. Which problem types are included?
The calculator includes rate-time-distance, percent change, simple interest, work rate, mixture, and age problems. These cover many classroom and homework scenarios with clear numeric relationships.
4. Why should I choose a problem type first?
Word problems often hide the formula inside text. Choosing the category first maps the story to the right equation, reduces mistakes, and makes the steps easier to follow.
5. Can I use decimals, percentages, and custom units?
Yes. Decimal values are supported, percentages are used where needed, and several templates include flexible unit fields so your result labels stay meaningful.
6. What does the graph show after solving?
The chart visualizes the selected scenario. Depending on the problem type, it may compare values, show change over time, or display concentration or completion trends.
7. When should I double-check the units?
Always check units before solving. Rate, time, volume, and percentage values must match the story. Unit mistakes are one of the most common reasons for wrong answers.
8. Can I save the solution for reports or class notes?
Yes. The result area includes CSV and PDF download buttons so you can keep a clean copy of the current solution for notes, assignments, or sharing.
