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 Order of Operations Solver?
AskSia's Order Of Operations Solver is an AI tool that evaluates any numeric or algebraic expression using the standard order of operations (PEMDAS): parentheses, exponents, multiplication and division (left to right), then addition and subtraction (left to right). AskSia handles nested parentheses, brackets, and braces, signed arithmetic, and follows the left-to-right rule for operations at the same priority level. Each step is labeled with the PEMDAS rule it applies.

Why AskSia Solver
Parentheses. Exponents. MD. AS.
PEMDAS applied in the correct order, left to right within each priority. AskSia labels every step so you can verify the rule.
Exponents before multiplication
Once parentheses are simplified, exponents are evaluated next. AskSia computes powers before any multiplication or division.
Exponents
Multiplication and division, left to right
At the same priority level, AskSia goes left to right, not multiplication-then-division. This matters for expressions like 12 / 3 * 2, which equals 8 (not 2).
MD left to right
Addition and subtraction, left to right
After multiplication and division, addition and subtraction performed left to right. Subtraction is treated as adding a negative when signs are confusing.
AS left to right
Negative numbers tracked
Signed arithmetic is shown explicitly: minus 3 + 7 = 4, minus 3 minus 7 = minus 10, (minus 2)^2 = 4 but minus 2^2 = minus 4. AskSia explains the difference.
Sign rules
Each step labeled
Every line in the work names the rule applied: 'parentheses', 'exponent', 'multiply', 'subtract'. The labels make the order easy to follow.

FAQ
Frequently asked questions.
What does PEMDAS stand for?
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. It is the standard order of operations used to evaluate any expression. The order is enforced in priority groups: parentheses are simplified first, then exponents, then multiplication and division together (left to right), then addition and subtraction together (left to right). Equivalent acronyms include BODMAS and BIDMAS used in some countries.
Why is multiplication and division grouped, and what does left-to-right mean?
Multiplication and division have the same priority, so they are performed left to right in the expression. For example, 12 / 3 * 2 equals 8: divide first to get 4, then multiply by 2. If you did multiplication first, you would get 12 / 6 = 2, which is wrong. The same rule applies to addition and subtraction at the lower priority. AskSia enforces left-to-right strictly.
How does AskSia handle (minus 2)^2 versus minus 2^2?
These are different. (minus 2)^2 = 4, because the parentheses say to square the entire negative 2: (minus 2) times (minus 2) = 4. But minus 2^2 = minus 4, because exponents take priority over the negative sign, so this means minus (2^2) = minus 4. AskSia tracks the parentheses and signs carefully and explains the difference in the work.
Can AskSia handle expressions with absolute values?
Yes. Absolute value bars (|x|) are treated as grouping symbols, evaluated like parentheses. The expression inside is simplified first, then the absolute value is taken. For example, |3 minus 7| = |minus 4| = 4. AskSia shows the inside simplification and the absolute-value step separately.
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.
