About the solver
How it works
The solver tool is backed by an AI model. The model reads your question and writes a plan of arithmetic steps.
The calculator then runs each step itself. It checks every step for division by zero, missing numbers and results outside the allowed range.
An answer is shown only when every step passes. Otherwise the solver explains why it cannot give one.
The AI model never supplies the final number. The calculator computes it from the steps.
What it can solve
Everyday arithmetic word problems, including:
- percentages, discounts, tips and sales tax
- wages and time
- speed and distance
- unit conversion and averages
- ratios and fractions
- profit and loss
- simple and compound interest
- basic area
What it cannot solve
It does not solve calculus, proofs, or problems that need information the question does not give.
It may misread unusual wording, so check the steps against your question.
Worked examples
The calculator’s arithmetic engine checked these examples. The accuracy of the AI model on other wordings has not been measured yet.
- $1,125. A student takes 5 courses at 3 credit hours each. Tuition is $75 per credit hour.
- $180. A store offers 25% off a $240 jacket.
- 60 mph. A train travels 180 miles in 3 hours.
- $3,080. A worker earns $22 an hour for 35 hours a week, over 4 weeks.
- $400. Sarah spent 30% of her savings and has $280 left.
- 5 cups. A recipe for 4 people needs 2 cups of flour; for 10 people.
The four-week month in the wage example is an assumption stated in the question.
