Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
What is the AskSia number solver?
The AskSia number solver is an AI tool for any task involving numbers: word problems that ask 'find the number' (set up an equation from the description and solve), comparing or ordering numbers in different forms, performing arithmetic with integers, fractions, decimals, and mixed numbers, converting between forms (fractions, decimals, percents, scientific notation), and classifying numbers (prime, composite, even, odd, perfect square, rational, irrational). Every solve shows each step with the operation named.

Why AskSia Solver
Numbers in every form, every operation.
Integers, fractions, decimals, percents, scientific notation. All four operations, comparisons, conversions, classifications. AskSia covers every number task.
Compare across number forms
To compare numbers in different forms (like 2/3 vs 0.7 vs 65%), AskSia converts everything to a common form (often decimal) before comparing. The comparison is shown with all numbers in one consistent format.
Cross-form compare
All operations, all types
Add, subtract, multiply, divide with integers, fractions, decimals, mixed numbers, or scientific notation. AskSia handles the operation in the form that's cleanest (often converting first), then converts the result if needed.
All operations
Convert between forms
Fraction to decimal (divide), decimal to fraction (place-value method), fraction or decimal to percent (multiply by 100), to or from scientific notation (move the decimal). AskSia handles every conversion direction.
Form conversion
Classify and identify
Is a number prime, composite, even, odd, perfect square, rational, irrational? AskSia checks the relevant property (divisibility tests for prime, square root for perfect square, decimal expansion for rational).
Classification
Number line and signed numbers
Number line representations for visualizing comparison, addition, and subtraction. Signed number arithmetic with the sign rules explained (same signs give positive product, opposite signs give negative).

Step 02
Watch the right operation
AskSia identifies the task (find, compare, operate, convert, classify) and applies the right method, with each step named and explained.
1
Set curves equal
x² = 2x → x = 0, x = 2
2
Set up the integral
A = ∫₀² (2x - x²) dx
3
Evaluate
A = [x² - x³/3]₀² = 4/3
Step 03

FAQ
Frequently asked questions.
How does AskSia solve 'find the number' word problems?
AskSia translates the verbal description into an algebraic equation. For 'I'm thinking of a number. When you double it and add 5, you get 17,' AskSia identifies the unknown as a variable (let x = the number), writes the relationship (2x + 5 = 17), solves step-by-step (subtract 5 to get 2x = 12; divide by 2 to get x = 6), and verifies by substituting back into the original description (2 × 6 + 5 = 17 ✓). The translation step is the trickiest part, and AskSia explains how each phrase in the problem maps to the algebra.
How does AskSia compare numbers in different forms?
AskSia converts all numbers to a common form (usually decimal) before comparing. For example, to order 2/3, 0.7, and 65%, AskSia converts: 2/3 ≈ 0.667, 0.7 = 0.7, 65% = 0.65. Then in decimal form, the order from smallest to largest is 0.65 < 0.667 < 0.7, which means 65% < 2/3 < 0.7. AskSia shows the conversion step explicitly so you can see why the order is what it is, and the final ordering is given in the original forms with comparison symbols.
How does AskSia convert between fractions, decimals, and percents?
Fraction to decimal: divide the numerator by the denominator (1/4 = 0.25). Decimal to fraction: use place value (0.25 = 25/100, then simplify to 1/4). Fraction or decimal to percent: multiply by 100 and add the % sign (0.25 = 25%; 1/4 = 25%). Percent to fraction or decimal: divide by 100 (25% = 0.25 = 1/4). AskSia handles every direction and shows the calculation explicitly. For repeating decimals (like 1/3 = 0.333...), AskSia uses bar notation or a fraction representation.
How does AskSia identify a prime number?
AskSia tests divisibility of the candidate number by every prime up to its square root. If none of those primes divides the candidate, it's prime. For example, to check if 97 is prime: √97 ≈ 9.8, so check primes 2, 3, 5, 7. 97 is odd (not divisible by 2), digit sum 16 (not divisible by 3), doesn't end in 0 or 5 (not divisible by 5), and 97 ÷ 7 ≈ 13.86 (not divisible by 7). So 97 is prime. AskSia shows each divisibility test explicitly. For composite numbers, AskSia returns the smallest prime factor along with the conclusion.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
